Hunger in young children of Mexican immigrant families

OBJECTIVE: To measure rates of hunger and food insecurity among young US-born Latino children with Mexican immigrant parents (Latinos) compared with a non-immigrant non-Latino population (non-Latinos) in a low-income clinic population. DESIGN, SETTING AND SUBJECTS: A repeated cross-sectional survey of 4278 caregivers of children < 3 years of age in the paediatric clinic of an urban county hospital for a 5-year period from 1998 to 2003. A total of 1310 respondents had a US-born child with at least one parent born in Mexico. They were compared with a reference group comprised of non-Latino US-born participants (n = 1805). Child hunger and household food insecurity were determined with the US Household Food Security Scale. RESULTS: Young Latino children had much higher rates of child hunger than non-Latinos, 6.8 versus 0.5%. Latino families also had higher rates of household food insecurity than non-Latinos, 53.1 versus 15.6%. Latino children remained much more likely to be hungry (odds ratio (OR) = 13.0, 95% confidence interval (CI) = 5.9-28.7, P < 0.01) and in household food-insecure households (OR = 6.6, 95% CI = 5.2-8.3, P < 0.01) than non-Latinos after controlling for the following variables in multivariate analysis: child's age, sex, maternal education level, single-headed household status, family size, young maternal age ( < 21 years), food stamp programme participation, TANF (Temporary Assistance to Needy Families, or 'welfare') programme participation and WIC (Women, Infants, and Children) usage, and reason for clinic visit (sick visit versus well-child). CONCLUSION: Young children in Mexican immigrant families are at especially high risk for hunger and household food insecurity compared with non-immigrant, non-Latino patients in a low-income paediatric clinic.     

Prevalence and predictors of food insecurity among low-income households in Los Angeles County

OBJECTIVES: To assess the prevalence and identify the predictors of food insecurity among households in Los Angeles County with incomes below 300% of the federal poverty level. METHODS: The Six-Item Short Form of the US Department of Agriculture's Household Food Security Scale was used as part of a 1999 county-wide, population-based, telephone survey. RESULTS: The prevalence of food insecurity was 24.4% and was inversely associated with household income. Other independent predictors of food insecurity included the presence of children in the household (odds ratio (OR) 1.7, 95% confidence interval (CI) 1.2-2.3) and a history of homelessness in the past five years (OR 5.6, 95% CI 3.4-9.4). CONCLUSION: Food insecurity is a significant public health problem among low-income households in Los Angeles County. Food assistance programmes should focus efforts on households living in and near poverty, those with children, and those with a history of homelessness.     

Food poverty and health among schoolchildren in Ireland: findings from the Health Behaviour in School-aged Children (HBSC) study

OBJECTIVES: To investigate the relationships between food poverty and food consumption, health and life satisfaction among schoolchildren. DESIGN: Analysis of the 2002 Health Behaviour in School-aged Children (HBSC) study, a cross-sectional survey that employs a self-completion questionnaire in a nationally representative random sample of school classrooms in the Republic of Ireland. SUBJECTS: A total of 8424 schoolchildren (aged 10-17 years) from 176 schools, with an 83% response rate from children. RESULTS: Food poverty was found to be similarly distributed among the three social classes (15.3% in the lower social classes, 15.9% in the middle social classes and 14.8% in the higher social classes). It was also found that schoolchildren reporting food poverty are less likely to eat fruits, vegetables and brown bread, odds ratio (OR) from 0.66 (95% confidence interval (CI) 0.45-0.87) to 0.81 (95% CI 0.63-0.99); more likely to eat crisps, fried potatoes and hamburgers, OR from 1.20 (95% CI 1.00-1.40) to 1.62 (95% CI 1.39-1.85); and more likely to miss breakfast on weekdays, OR from 1.29 (95% CI 0.33-1.59) to 1.72 (95% CI 1.50-1.95). The risk of somatic and mental symptoms is also increased, OR from 1.48 (95% CI 1.18-1.78) to 2.57 (95% CI 2.33-2.81); as are negative health perceptions, OR from 0.63 (95% CI 0.43-0.83) to 0.52 (95% CI 0.28-0.76) and measures of life dissatisfaction, OR from 1.88 (95% CI 1.64-2.12) to 2.25 (95% CI 2.05-2.45). Similar results were found for life dissatisfaction in an international comparison of 32 countries. All analyses were adjusted for age and social class. CONCLUSIONS: Food poverty in schoolchildren is not restricted to those from lower social class families, is associated with a substantial risk to physical and mental health and well-being, and requires the increased attention of policy makers and practitioners.     

Who is food-insecure in California? Findings from the California Women's Health Survey, 2004

OBJECTIVE: To identify factors associated with food insecurity in California women. DESIGN: The California Women's Health Survey is an ongoing annual telephone survey that collects data about health-related attitudes and behaviours from a randomly selected sample of women. Food insecurity of the women was measured by a 6-item subset of the Food Security Module. Statistical procedures included chi-square tests, t-tests, logistic regression analysis and analysis of covariance. SETTING: California, USA. SUBJECTS: Four thousand and thirty-seven women (18 years or older). RESULTS: Prevalence of food insecurity was 25.7%. After controlling for income, factors associated with greater food insecurity were Hispanic or Black race/ethnicity; less than a 12th grade education; being unmarried; less than 55 years old; being Spanish-speaking; having spent less than half of one's life in the USA; sadness/depression; feeling overwhelmed; poor physical/mental health interfering with activities; and fair to poor general health. Among Food Stamp Program (FSP) participants, 71% were food-insecure. Among FSP-eligible women who had not applied for the programme, the prevalence of food insecurity was lower among women responding that they did not need food stamps than in women giving other reasons for not applying (23.9% vs. 66.9%, P < 0.001). Factors associated with food insecurity in FSP recipients included being unable to make food stamps last for 30 days, feeling overwhelmed, and having a birthplace in Mexico or Central America. CONCLUSIONS: Along with several socio-economic variables, poor physical and mental health is associated with food insecurity. Whether food insecurity is a cause or effect of poor health remains in question.     

Food insecurity, weight control practices and body mass index in adolescents

OBJECTIVE: We investigated whether experienced food insecurity was associated with weight control behaviour of adolescents. DESIGN: A national survey of 16-year-old students with the six-item food security scale, questions concerning intentions of trying to change weight, physical activity patterns, and measurement of height and weight. SETTING: Representative sample of 29 schools in Trinidad, West Indies. SUBJECTS: Data analysed for 1903 subjects including 1484 who were food-secure and 419 who were food-insecure. RESULTS: In the whole sample, food security status did not vary by body mass index (BMI) category. 'Trying to gain weight' and 'spending most free time in activities involving little physical effort' were each associated with lower BMI. 'Trying to gain weight' was more frequent in food-insecure subjects (135, 32%) than in food-secure subjects (369, 25%, P = 0.012). After adjustment for BMI, age, sex, ethnicity and socio-economic variables, the adjusted odds ratio (OR) of 'trying to gain weight' for food-insecure subjects was 1.39 (95% confidence interval (CI) 1.07-1.82, P = 0.014). Food-insecure subjects (197, 47%) were more likely than food-secure subjects (575, 39%) to report that most of their free time was spent doing things that involved little physical effort (P = 0.003). This association was not explained by adjustment for BMI, age, sex and ethnicity (OR = 1.41, 95% CI 1.13-1.76, P = 0.002) or additional socio-economic variables (OR = 1.27, 95% CI 1.02-1.57, P = 0.033). CONCLUSIONS: Adolescents who experience food insecurity are more likely to intend to gain weight but engage in less physical activity than food-secure subjects with the same BMI.     

Acculturation, economics and food insecurity among refugees resettled in the USA: a case study of West African refugees

OBJECTIVES: To assess the occurrence and severity of food insecurity, and examine associations between food insecurity and measures of socio-economic status and indicators of acculturation. DESIGN: Structured interviews among a non-probability sample of West African refugees at baseline and 6 months' follow-up.Setting Mid-sized city in north-eastern USA. SUBJECTS: One hundred and one caregivers with children under the age of 5 years and who have been living the USA for fewer than 4 years. RESULTS: Food insecurity was indicated in approximately half of households (53%). The occurrence of food insecurity was associated with measures of socio-economic status such as income, employment status and participation in the Food Stamp Program (P < 0.05). Measures of acculturation such as difficulty in the shopping environment and language difficulty were also associated with the occurrence and severity of food insecurity, as was time lived in the USA (P < 0.05). Among households who had been in the USA for 1 year or less, food insecurity was indicated in 73%, whereas among households who had been in the USA for at least 3 years food insecurity was indicted in 33%. CONCLUSIONS: Refugees are a potentially vulnerable group and our results echo others in suggesting a need for more thorough monitoring of the health and well-being of recently resettled refugees. These results also suggest that reliance on employment as the sole indicator of success in the resettlement process may be too narrow an indicator. Future research should focus on a wider range of measures of health and well-being.     

Green tea consumption in everyday life and mental health

OBJECTIVE: Green tea has been widely acknowledged in Japan to induce a pleasurable mental feeling. Recent laboratory studies have suggested positive psychological effects as a result of consuming green tea. The present study examined whether green tea consumption in everyday life in Japan is associated with positive mental health. DESIGN: A cross-sectional study was performed in February-March 2002. SETTING AND SUBJECTS: The subjects of the study consisted of a general population of 600 Japanese aged 20-69 years. Responses of 380 subjects, obtained by home-visit interview, were analysed. The questionnaire inquired about consumption of brewed green tea and other beverages, perceived mental health status, lifestyle and others. The 12-item General Health Questionnaire (GHQ 12) was used for the assessment of mental ill-health (GHQ score >or=4). RESULTS: After adjustments for age, area, perceived mental stress, lifestyle and daily caffeine intake, the consumption of brewed green tea was not statistically associated with any decrease in risk of mental ill-health among either males or females (odds ratio (OR)=0.78, 95% confidence interval (CI)=0.47-1.29 for males; OR=0.77, 95% CI=0.51-1.14 for females). Daily caffeine intake (100 mg) inclusive of green tea, black tea, coffee and other caffeine-containing beverages was associated with a higher risk of mental ill-health among females (OR=1.26, 95% CI=1.01-1.56). CONCLUSIONS: The results provide population-based evidence on the consumption of brewed green tea in everyday life and mental health, together with information on consumption patterns of various beverages and lifestyles.     

Fruit and vegetable consumption and self-reported functional health in men and women in the European Prospective Investigation into Cancer-Norfolk (EPIC-Norfolk): a population-based cross-sectional study

OBJECTIVES: To investigate the association between fruit and vegetable consumption and self-reported physical and mental functional health measured by an anglicised short-form 36-item questionnaire (UK SF-36). DESIGN: Population-based cross-sectional study. SETTING: General community in Norfolk, UK. SUBJECTS: A total of 16,792 men and women aged 40-79 years recruited from general practice population registers as part of the European Prospective Investigation into Cancer (EPIC)-Norfolk study, who completed food-frequency questionnaires in 1993-1997 and Health and Life Experiences Questionnaires 18 months later, were enrolled in the study. RESULTS: Mean SF-36 physical component summary scores increased significantly with increasing total fruit and vegetable consumption in both men and women (P < 0.0001 for trend). Men and women in the top quartile of consumption compared with the bottom quartile had a significantly higher likelihood of reporting good physical health (defined as a score > or = 55); odds ratio (OR) 1.30, 95% confidence interval (CI) 1.11-1.53 for men and OR 1.28, 95% CI 1.11-1.48 for women, after controlling for age, body mass index, smoking, education, social class, prevalent illness and total energy intake. Exclusion of current smokers and people with prevalent illness did not alter the associations. CONCLUSION: Higher fruit and vegetable consumption is associated with better self-reported physical functional health within a general population. Increasing daily intake by two portions of fruit and vegetables was associated with an 11% higher likelihood of good functional health. Since the current average consumption of fruit and vegetables in the UK is about three portions, the recommended 'five a day' strategy may have additional benefit for functional as well as other health outcomes in the population.     

Food insecurity, malnutrition and mortality in Maewo and Ambae Islands, Vanuatu

CONTEXT: This paper reports on findings from the ex-post evaluation of the Maewo Capacity Building project in Maewo Island, Vanuatu, which was funded by World Vision Australia. OBJECTIVES: To examine the extent to which the infrastructure and systems left behind by the project contributed to the improvement of household food security and health and nutritional outcomes in Maewo Island, using Ambae Island as a comparator. SETTING: Two-stage cluster survey conducted from 6 to 20 July 2004, which included anthropometric measures and 4.5-year retrospective mortality data collection. PARTICIPANTS: A total of 406 households in Maewo comprising 1623 people and 411 households in Ambae comprising 1799 people. MAIN OUTCOME MEASURES: Household food insecurity, crude mortality rate (CMR), under-five mortality rate (U5MR) and malnutrition prevalence among children. RESULTS: The prevalence of food insecurity without hunger was estimated at 15.3% (95% confidence interval (CI): 12.1, 19.2%) in Maewo versus 38.2% (95% CI: 33.6, 43.0%) in Ambae, while food insecurity with hunger in children did not vary by location. After controlling for the child's age and gender, children in Maewo had higher weight-for-age and height-for-age Z-scores than children of the same age in Ambae. The CMR was lower in Maewo (CMR = 0.47/10 000 per day, 95% CI: 0.39, 0.55) than in Ambae (CMR=0.59/10 000 per day, 95% CI: 0.51, 0.67) but no difference existed in U5MR. The major causes of death were similar in both locations, with frequently reported causes being malaria, acute respiratory infection and diarrhoeal disease. CONCLUSIONS: Project initiatives in Maewo Island have reduced the risks of mortality and malnutrition. Using a cross-sectional 'external control group' design, this paper demonstrates that it is possible to draw conclusions about project effectiveness where baseline data are incomplete or absent. Shifting from donor-driven evaluations to impact evaluations has greater learning value for the organisation, and greater value when reporting back to the beneficiaries about project impact and transformational development in their community. Public health nutritionists working in the field are well versed in the collection and interpretation of anthropometric data for evaluation of nutritional interventions such as emergency feeding programmes. These same skills can be used to conduct impact evaluations, even some time after project completion, and elucidate lessons to be learned and shared. These skills can also be applied more widely to projects which impact on the longer-term nutritional status of communities and their food security.     

Prevalence of obesity, food choices and socio-economic status: a cross-sectional study in the north-west of Iran

AIM: To document the epidemiological features and influencing factors of obesity in the north-west of Iran, to provide baseline information for setting up a regional population-based centre to control and prevent obesity-related disorders in the area. METHODS: In this cross-sectional study, a total of 300 subjects were selected/studied in Tabriz, one of the major cities in Iran. Data on basic characteristics, anthropometric measurements, dietary assessment and physical activity were collected. Obesity was defined as body mass index > or =30 kg m(-2) for both women and men. RESULTS: Total prevalence of obesity in the area was 22.4% (95% confidence interval (CI): 18.0-27.6). The prevalence of obesity was 24% (95% CI: 18.5-31.4) for women and 18% (95% CI: 12.5-25.6) for men. For both women and men obesity prevalence showed a positive association with age (P<0.001), while there was a negative correlation of obesity with education and income (P<0.001). Fruit consumption decreased the risk of obesity in both women and men (odds ratio (OR)=0.60, 95% CI: 0.49-0.71 vs. OR=0.62, 95% CI: 0.51-0.74, respectively). The same significant pattern was observed for the consumption of green vegetables (OR=0.71, 95% CI: 0.57-0.63 vs. OR=0.86, 95% CI: 0.77-0.98 for women and men, respectively), legumes (OR=0.70, 95% CI: 0.59-0.84 vs. OR=0.78, 95% CI: 0.66-0.91 for women and men, respectively) and dairy products (OR=0.73, 95% CI: 0.61-0.91 vs. OR=0.77, 95% CI: 0.63-0.93 for women and men, respectively). CONCLUSIONS: Our study showed that educational attainment, higher income and consumption of certain food groups (i.e. vegetables, fruits, legumes and dairy products) may decrease the risk of obesity. Our findings also indicate the crucial necessity of establishing a population-based centre for obesity in the area. The essential information is now achieved to propose to local health authorities to act accordingly. However, more population-based investigations on dietary choices are needed to develop effective preventive strategies to control overweight and obesity disorders in different regions.     

Leisure-time and occupational physical activity in relation to cardiovascular risk factors and eating habits in French adults

OBJECTIVE: To investigate the relationships of two main physical activity domains (during leisure and at work) with cardiovascular risk factors and eating habits. DESIGN: Cross-sectional study. SETTING: Preventive medicine centre. SUBJECTS: In 5478 adults (32% women, aged 20-80 years) who consecutively underwent a standardised health examination, leisure-time physical activity (LTPA; i.e. non-sport leisure and sport activities), occupational physical activity (OPA) and eating habits were assessed by self-administered questionnaires. We analysed sex-specific relationships of LTPA and OPA (in quartiles) with (1) various cardiovascular risk factors and (2) eating habits using analysis of variance and logistic regression, respectively. RESULTS: In both genders, with and without adjustment for education in addition to age, LTPA was associated negatively with body mass index, body fat, waist circumference, resting heart rate, diastolic blood pressure and triglycerides, and positively associated with high-density lipoprotein cholesterol (all P < or = 0.005). OPA adjusted for age only was positively associated with most cardiovascular risk factors but these associations were not significant after further adjustment on education (except for waist circumference in women). Age- and education-adjusted LTPA was associated with increased frequency of consumption of fruits (odds ratio (OR) = 2.05, 95% confidence interval (CI) 1.68-2.52 in men; OR = 1.90, 95% CI 1.41-2.05 in women) and vegetables (OR = 1.81, 95% CI 1.48-2.21 in men; OR = 2.22, 95% CI 1.66-2.97 in women). CONCLUSIONS: The data emphasise the favourable associations of LTPA, a modifiable behaviour, with various cardiovascular risk factors and healthy eating habits. The results also suggest that the relationships of OPA with cardiovascular risk factors depend, at least in part, on socio-economic status as reflected by educational level.     

Correlates of childhood obesity in Athens, Greece

OBJECTIVE: Childhood obesity is a growing public health problem. We have examined the association between sociodemographic profile and eating and physical activity patterns with overweight among primary-school students in Athens, Greece. DESIGN: Cross-sectional study. SETTING: Eleven primary schools in the greater Athens area, Greece. SUBJECTS: A total of 633 children aged 10-12 years (50 % boys, 50 % girls) were interviewed in person during spring 2003. Multivariate logistic regression was used to investigate the association between eating and physical activity patterns and overweight (> or =85th sex- and age-specific BMI centile). Results are presented as odds ratios and 95 % confidence intervals. RESULTS: Overweight was more common among girls than among boys (OR=1.73; 95% CI 1.11, 2.69) and substantially less common among children born outside Greece (OR=0.46; CI 0.22, 0.95). Reported physical activity (per 1.5 h per day) was unrelated to overweight (OR=0.97; CI 0.85, 1.12) but patent physical inactivity, operationalised as time spent watching television or working/playing with the computer (per 1.5 h per day) was a highly significant predictor of overweight (OR=1.20; CI 1.05, 1.36). Composition of diet was unrelated to overweight but the daily number of eating occasions, controlling for total energy intake, was significantly inversely associated with overweight (OR=0.61; CI 0.48, 0.76). CONCLUSIONS: The principal factor underlying overweight among children in Athens appears to be the extended inactivity imposed by modern childhood lifestyles. An intriguing finding is that spreading a given energy intake over several eating occasions was inversely associated with the likelihood of childhood obesity.     

Seasonal food insecurity and perceived social support in rural Tanzania

OBJECTIVES: To examine whether the occurrence of seasonal food insecurity was related to ethnicity, household wealth and perceived social support, and to assess whether social support was more efficacious in protecting against food insecurity in wealthier households. Secondary objectives were to assess the association between past food insecurity, current dietary intake and perceived health. DESIGN, SETTING AND SUBJECTS: A sample of 208 randomly selected mothers from two ethnic groups living in the same villages in rural Tanzania participated in a cross-sectional survey. RESULTS: Food insecurity was highly prevalent in this area, particularly among the poorer ethnic group. Half of ethnically Sukuma households fell into the most food-secure category, compared with only 20% of ethnically Pimbwe households. Among both groups, measures of household wealth and social support were strongly associated with food security. Interestingly, social support appeared to be more effective among the wealthier ethnic group/community. Past food insecurity was also related to current indicators of dietary intake and women's self-perceptions of health. CONCLUSION: Greater social support is associated with food security, suggesting that it may protect against the occurrence of seasonal food insecurity. Social support also interacts with wealth to offer greater protection against food insecurity, suggesting that increasing wealth at the community level may influence food insecurity through both direct and indirect means. Seasonal food insecurity also appears to have lasting effects that likely create and reinforce poverty.     

Protective effect of yoghurt consumption on Helicobacter pylori seropositivity in a Mexican population

OBJECTIVE: The aim of the study was to determine the relationship between fermented and unfermented dairy product consumption and Helicobacter pylori seropositivity in a Mexican population. DESIGN: Dietary interviews were conducted as part of a population-based case-control study in 2005. Serum was obtained for each participant to determine H. pylori seropositivity status. Adjusted odds ratios were estimated from multivariate logistic regression models. SETTING: Mexico City, Mexico. SUBJECTS: A random sample of 464 healthy adult residents. RESULTS: The overall seroprevalence of H. pylori in the study sample was 75.4%. In fully adjusted models, compared with those who did not consume yoghurt, there was a protective effect of eating up to one serving per week of yoghurt and more than one serving per week of yoghurt (odds ratio (OR) = 0.57, 95% confidence interval (CI) 0.35-0.94 and OR = 0.45, 95% CI 0.24-0.86, respectively), with a P for trend of 0.01. There were no effects for the consumption of unfermented dairy products (milk and cheese). CONCLUSIONS: This study suggests that yoghurt consumption may have a protective effect against H. pylori seropositivity. Additional studies are needed to determine whether consumption of yoghurt or other fermented dairy products can prevent or eradicate H. pylori infection.     

Prevalence of overweight and obesity among school-aged children in urban, rural and mountain areas of the Veneto Region, Italy

OBJECTIVE: To define the prevalence of overweight and obesity among school-aged children resident in mountain areas, rural areas and urban areas.Design, setting and subjectsThe sample (n = 12 832; 50.7% boys) included 9- and 11-year-old children of the Veneto Region of north-east Italy. Overweight and obesity status were determined using the International Obesity Task Force cut-off points for body mass index. The prevalence of overweight and obese subjects was calculated with a confidence interval of 95%. The Mantel-Haenszel method was used to compare the combined prevalence of overweight and obesity among children resident in mountain areas, rural areas and urban areas. RESULTS: Among boys the prevalence of overweight was 21.06%, while obesity prevalence was 5.92%; among girls overweight prevalence was 21.30%, while obesity prevalence was 5.15%. The prevalence was higher among 11-year-old boys (odds ratio (OR) = 1.19; 95% confidence interval (CI): 1.06-1.33) and 9-year-old girls (OR = 1.13; 95% CI: 1.01-1.26). Children resident in rural areas presented a higher risk of overweight and obesity compared with children resident in mountain areas (Mantel-Haenszel OR = 1.27; 95% CI: 1.13-1.42; chi2 = 17.55; P < 0.0001) and in urban areas (Mantel-Haenszel OR = 1.18; 95% CI: 1.07-1.31; chi2 = 10.39; P < 0.001). CONCLUSIONS: A relevant prevalence of overweight and obesity was found; the excess weight concerns one child in four. There are differences linked to different geographical areas that must be further investigated.     

Habitual fish consumption and risk of incident stroke: the European Prospective Investigation into Cancer (EPIC)-Norfolk prospective population study

OBJECTIVES: To examine the association between fish consumption and stroke risk. DESIGN: Prospective population cohort study.Setting: Norfolk, UK cohort of the European Prospective Investigation into Cancer (EPIC-Norfolk). SUBJECTS: Subjects were 24 312 men and women aged 40-79 years who had no previous history of stroke at baseline.Methods: Fish consumption was assessed using a food-frequency questionnaire at baseline in 1993-1997 and stroke incidence ascertained to 2004. RESULTS: A total of 421 incident strokes were identified (mean follow-up=8.5 years, total person-years=209 238). There were no significant relationships between total fish, shellfish or fish roe consumption and risk of stroke in men and women after adjusting for age, systolic blood pressure, body mass index, smoking, cholesterol, diabetes, physical activity, alcohol consumption, fish oil supplement use and total energy intake using Cox regression analyses. Oily fish consumption was significantly lower in women who subsequently had a stroke (odds ratio (OR) for consumers vs. non-consumers=0.69, 95% confidence interval (CI) 0.51-0.94, P=0.02). The trend in men was similar but not significant (OR for consumers vs. non-consumers=0.88, 95% CI 0.65-1.19, P=0.41). CONCLUSIONS: There was no consistent relationship between fish consumption and stroke in this British population. Inconsistencies in the observed health effects of fish consumption in different populations may reflect different patterns and type of fish consumed and preparation methods.     

The California Agricultural Workers Health Survey

The California Agricultural Workers Health Survey was a statewide cross-sectional household survey of 970 hired farm laborers. Randomly selected participants residing in randomly selected dwellings were recruited in seven communities representing all of the state's agricultural regions. Participants were interviewed in their preferred language by professional staff. The response rate was 83%. The comprehensive interview included self-reported health conditions, doctor-reported health conditions, work history, workplace health conditions, field sanitation, and work-related injuries. A farm workplace injury during the twelve-month period prior to the interview was reported by 6% of male workers (95% CI: 4% - 8%) and 2% of female workers (95% CI: 1% - 3%). Significant numbers of both male (41%) and female (40%) workers reported persistent pain (every day for more than one week) in the back, neck, knees, shoulders, hands, feet, or multiple body parts. The number of body parts in which female workers reported persistent pain correlated with increased years of U.S. hired farm work (Spearman r = 0.24, p < 0.01). Direct contact with pesticides from being sprayed or drifted upon among both male and female workers was associated with multiple workplace health conditions such as irritated, itchy, or water eyes (male: OR 2.9, 95% CI: 1.6 - 5.0; female: OR 13.8, 95% CI: 4.3 - 44.7). Persistent stomach aches among male and female participants was associated with being required to taste unwashed grapes for sweetness while picking (male: OR 4.6, 95% CI: 2.1 - 9.9; female: OR 5.8, 95% CI: 2.6 - 12.6).     

Women's input into household decisions and their nutritional status in three resource-constrained settings

OBJECTIVE: To understand the role of women's input into household decisions as a possible factor contributing to women's undernutrition in settings where HIV/AIDS and drought have constrained household resources. DESIGN AND SETTING: Three cross-sectional surveys of non-pregnant women in partnerships without a birth in the last 3 months were analysed. Factors associated with chronic energy deficiency (CED), defined as body mass index of<18.5 kg m(-2), were assessed among 1920 women in Zimbabwe, 2870 women in Zambia and 6219 women in Malawi. RESULTS: Prevalence of CED was 4.2% in Zimbabwe, 13.5% in Zambia and 6.7% in Malawi. In Malawi, women with less input into decisions were more likely to have CED. After multivariable adjustment, each additional decision made by the partner increased the odds of CED in Malawi by 1.08 (95% confidence interval (CI) 1.02-1.15); each additional decision made by the woman decreased the odds of CED by 0.90 (95% CI 0.88-0.97). Malawian women with all the final say or with partners with no final say had significantly more CED than expected (odds ratio (OR)=2.88, 95% CI 1.42-5.83 and OR=1.64, 95% CI 1.06-2.52, respectively), and removing these points increased the magnitude and significance of the linear trends. In Zambia, the relationship was found for urban women only and no associations were found in Zimbabwe. CONCLUSIONS: Input into household decisions may be a key factor in the cycle of drought and CED. Women with both low input and CED may lose productive capacity, putting them at greater risk of food insecurity and potentially HIV/AIDS in high prevalence settings.     

What young Dutch adults say they do to keep from gaining weight: self-reported prevalence of overeating, compensatory behaviours and specific weight control behaviours

OBJECTIVE: The aim of this study was to explore the prevalence of and differences in self-reported occasions of overeating (such as at celebrations and other parties), compensatory behaviours and specific weight gain prevention strategies among young Dutch adults according to sociodemographics and overweight status. DESIGN AND SUBJECTS: Cross-sectional data were analysed from Dutch adults aged 20-40 years, recruited from an Internet research panel (n = 857, response rate = 76.6%). Using electronic questionnaires, self-report data were collected on sociodemographics, body mass index (BMI), occasions of overeating, compensatory behaviours, and diet and physical activity used as weight gain prevention strategies. Associations were tested using multiple linear and logistic regression analyses. RESULTS: Of the participants, 48.6% reported occasions of overeating at least once a week during the 4-week period, 44.6% reported compensating for these occasions and 72.9% reported engaging in dietary and physical activities specifically for weight gain prevention purposes. Only 32.1% of the respondents reported using the recommended combination of diet and physical activity as a weight gain prevention strategy. In addition, results showed that overweight people (BMI > or = 25 kg m-2) and women were more likely to report overeating than people with healthy body weights (odds ratio (OR) = 1.79; 95% confidence interval (CI) 1.32-2.42) and men (OR = 1.50; 95% CI 1.14-1.97). Overweight people, women and people who regularly reported overeating were also significantly more likely to report compensatory behaviours by eating less and to report specific weight gain prevention strategies using diet and physical activity. CONCLUSION: The present study suggests that people experience frequent occasions of overeating and try to compensate for such occasions in different ways. However, the combination of dietary changes and physical activity recommended by experts was seldom reported.
