Countries in the Commonwealth of Independent States made little progress in child nutrition and mortality between 1990 and 2005. The present paper assesses the nutritional status of children <5 years of age and discusses possible strategies for improvement.
Methods
Data on low birth weight, infant and young child feeding, underweight, overweight and micronutrient deficiencies were compiled from available reports and databases, complemented through questionnaires to UNICEF Country Offices, and analysed by country, age, gender, urban/rural residence, maternal education and wealth quintiles.
Results
Exclusive breast-feeding in the first 6 months and continuing breast-feeding up to 2 years fall short of WHO and UNICEF recommendations. Complementary foods are introduced too early and may be poor in protein and micronutrients. Stunting and underweight are prevalent, especially in children aged 12 to 35 months; overweight is even more prevalent. Vitamin A and I deficiencies are still present in some countries, despite current control efforts. Anaemia ranges between 20 % and 40 %. Higher rates of malnutrition are found in rural areas, children of less educated mothers and lower-income families.
Discussion
Current public health strategies should be redirected to address: (i) overall protection, promotion and support of infant and young child feeding, in addition to breast-feeding; (ii) overweight, in addition to underweight and stunting; and (iii) malnutrition as a whole, in addition to micronutrient deficiencies. An equity lens should be used in developing policies and plans and implementing and monitoring programmes. Capacity building, cross-sectoral action, improved data collection within adequate legal frameworks and community engagement should be the pillars of redirected strategies.
To examine the association between household socio-economic status (SES) at birth and poor infant growth such as small for gestational age (SGA) and stunting across two different socio-cultural settings: South Africa and the Philippines.
Design
Data were from two longitudinal birth cohorts, the Birth to Twenty (Bt20) study in South Africa and the Cebu Longitudinal Health and Nutrition Survey (CLHNS) in the Philippines.
Subjects
Bt20 infants (n 2293 total; reduced to 758 (SGA), 450 (stunting 1 year) and 401 (stunting 2 years)) and CLHNS infants (n 2513 total; reduced to 2161 (SGA), 1820 (stunting 1 year) and 1710 (stunting 2 years)).
Results
CLHNS infants were significantly more likely to be born SGA (20·9 v. 11·7 %) and be stunted at 1 year (32·6 v. 8·7 %) and 2 years (48·9 v. 21·1 %) compared with Bt20 infants. Logistic regression analyses showed that SES (index) was a significant predictor of stunting at 1 and 2 years of age in the CLHNS cohort. SES (index or individual variables) was not a significant predictor of SGA in either cohort, or of stunting in the Bt20 cohort. Maternal education, ownership of a television and toilet facilities were all independent predictors of stunting in the CLHNS cohort.
Conclusions
The social and economic milieu within the Philippines appears to place CLHNS infants at greater risk of being born SGA and being stunted compared with Bt20 infants. The present research highlights the importance of investigating the individual SES variables that predict infantile growth faltering, to identify the key areas for context-specific policy development and intervention.
Women of lower educational attainment have less balanced and varied diets than women of higher educational attainment. The diets of women are vital to the long-term health of their offspring. The present study aimed to identify factors that influence the food choices of women with lower educational attainment and how women could be helped to improve those choices.
Design
We conducted eight focus group discussions with women of lower educational attainment to identify these factors. We contrasted the results of these discussions with those from three focus group discussions with women of higher educational attainment.
Setting
Southampton, UK.
Subjects
Forty-two white Caucasian women of lower educational attainment and fourteen of higher educational attainment aged 18 to 44 years.
Results
The dominant theme in discussions with women of lower educational attainment was their sense that they lacked control over food choices for themselves and their families. Partners and children exerted a high degree of control over which foods were bought and prepared. Women’s perceptions of the cost of healthy food, the need to avoid waste, being trapped at home surrounded by opportunities to snack, and having limited skill and experience with food, all contributed to their sense they lacked control over their own and their family’s food choices.
Conclusions
An intervention to improve the food choices of women with lower educational attainment needs to increase their sense of control over their diet and the foods they buy. This might include increasing their skills in food preparation.
To determine the extent to which differences in sociodemographic, dietary and lifestyle characteristics exist between users of different types of dietary supplements and supplement non-users.
Design
We analysed cross-sectional data obtained from self-administered questionnaires completed at baseline by participants in The Tomorrow Project; a prospective cohort study in Alberta, Canada. Participants who used at least one type of dietary supplement at least weekly in the year prior to questionnaire completion were defined as supplement users, while the remainder were classified as non-users. Seven discrete user categories were created: multivitamins (+/− minerals) only, specific nutritional supplements only, herbal/other supplements only, and all possible combinations. Differences in sociodemographic, dietary and lifestyle characteristics between different groups of supplement users and non-users were analysed using Rao–Scott χ2 tests and multinomial logistic regression.
Subjects and setting
Subjects were 5067 men and 7439 women, aged 35–69 years, recruited by random digit dialling throughout Alberta.
Results
Supplement use was extensive in this study population (69·8 %). Users of herbal/other supplements only, and women who used multivitamins only, tended to report dietary and lifestyle characteristics that were not significantly different from non-users. In contrast, those who reported using a combination of multivitamins, specific nutritional and herbal/other supplements were more likely than non-users to report behaviours and characteristics consistent with current health guidelines.
Conclusions
Dichotomizing participants as supplement users or non-users is likely to mask further differences in sociodemographic, dietary and lifestyle characteristics among users of different types of supplements. This may have implications for analysis and interpretation of observational studies.
Food-insecure populations employ multiple strategies to ensure adequate household food supplies. These strategies may increase the risk of overweight and obesity. However, existing literature reports conflicting associations between these strategies and BMI. The objective of the present study was to examine whether food insecurity and strategies for managing food insecurity are associated with BMI in adults.
Design, setting and subjects
In 2005, RTI International and Project Bread conducted a representative survey of 435 adult residents of low-income census tracts in Massachusetts. Food insecurity was assessed using the US Department of Agriculture’s eighteen-item Household Food Security Module.
Results
The prevalence of overweight and obesity was 51 % and 25 %, respectively. After adjusting for age, sex, sociodemographic characteristics and food insecurity, both participation in the Food Stamp Program (FSP) and participation in any federal nutrition programme 12 months prior to the survey were each associated with an approximate 3·0 kg/m2 higher adult BMI. In the subset of current FSP participants (n 77), participation for ≥6 months was associated with an 11·3 kg/m2 lower BMI compared with participation for <6 months. Respondents who consumed fast foods in the previous month had a mean BMI that was 2·4 kg/m2 higher than those who did not. Food insecurity was not associated with BMI after adjustment for sociodemographic characteristics and FSP participation.
Conclusions
Participation in federal nutrition programmes and consumption of fast food were each associated with higher adult BMI independent of food insecurity and other sociodemographic factors. However, prolonged participation in the FSP was associated with lower BMI.
To assess which socio-economic indicator best predicts overweight in the European Union: educational attainment, occupational class or household income.
Setting
The prevalence of overweight is strongly related to socio-economic position. The relative importance of different socio-economic dimensions is uncertain, and might vary between countries.
Design and subjects
Cross-sectional self-report data of the European Community Household Panel were obtained from nine countries (n 52 855; age 25–64 years). Uni- and multivariate regression analyses were employed to predict overweight (BMI ≥ 25 kg/m2) in relationship to socio-economic indicators. Occupational class was measured using the new European Socioeconomic Classification.
Results
Large socio-economic differences in overweight were observed in all countries, especially for women. For both sexes, a low educational attainment was the strongest predictor of overweight. After controlling for education, overweight was negatively related to household income in women, but positively in men. Similar patterns were found for occupational class. For women, but not for men, educational inequalities in overweight were generally greater in Southern European countries. A similar pattern of inequalities in overweight was observed for all ages between 25 and 64 years.
Conclusions
Across Europe, overweight was more strongly and more consistently related to educational attainment than to occupational class or household income. People with lower educational attainment should be a specific target group for programmes and policies that aim to prevent overweight.
The present paper examines the relationship between social factors, food consumption during television viewing, and overall television viewing and how these are associated with BMI when the role of familial and social factors are considered in a population-based birth cohort of pre-school children from Québec (Canada).
Methods
The analyses were performed using data from the Longitudinal Study of Child Development in Québec (1998–2002) (LSCDQ). The study follows a representative sample (n 2103) of children born in 1998 in the Canadian province of Québec. A nutrition assessment was conducted on 1549 children aged 4·5 years and included a 24 h dietary recall, an eating behaviour and television viewing questionnaire, and a measurement of children’s heights and weights. Statistical analyses were performed.
Results
Nearly one-quarter of children ate at least twice daily in front of the television. Children who consumed snacks while watching television on a daily basis had higher BMI than children who did so less frequently. Children who ate snacks in front of the television every day, or some times during the week, ate more carbohydrates (total), more fat and less protein, fewer fruits and vegetables, and drank soft drinks more often than children who never ate snacks in front of the television.
Conclusions
Health professionals should target parents of children at risk of overweight/obesity with focused strategies to help children change the types of foods consumed during television viewing and to reduce the time spent watching television, particularly during meal times, which may change children’s dietary intake and eating patterns.
To document the prevalence and the socio-spatial variations of obesity and to identify individual and household characteristics, lifestyles and dietary practices contributing to obesity and its socio-spatial distribution.
Design
Population-based cross-sectional survey. We selected 1570 households from four strata characterised as unstructured and low building-density (ULBD), unstructured and high building-density (UHBD), structured and low building-density (SLBD) and structured and high building-density (SHBD) areas. Structured areas are those that were allotted by the township authority (cadastral services), with public services; unstructured areas refer to those developed with no cadastral organisation.
Setting
Ouagadougou, the capital city of Burkina Faso.
Subjects
BMI was calculated in 2022 adults aged 35 years and above who were classified as obese when their BMI was ≥30 kg/m2. Obesity was investigated in relation to household and individual characteristics, lifestyles and dietary practices; adjusted odds ratios with 95 % confidence intervals were derived from a logistic regression model.
Results
The overall prevalence of obesity was 14·7 % (males 5·5 % and females 21·9 %). Age, gender, household equipment index, usual transport with motor vehicles and micronutrient-rich food consumption were associated with obesity. After adjustment for these factors, obesity remained associated with the area of residence: residents from SHBD areas were more likely to be obese than those from ULBD areas (OR = 1·41; 95 % CI 2·59,4·76).
Conclusions
Obesity in Ouagadougou is a preoccupant problem that calls for more consideration. Thorough investigation is needed to assess the environmental factors that contribute to the socio-spatial disparity of obesity.
To determine factors associated with Food Stamp Program (FSP) participation in a potentially eligible California population.
Design
The California Women’s Health Survey is an on-going annual telephone survey that collects data about health-related attitudes and behaviours from a randomly selected sample of women. Statistical procedures included χ2 and logistic regression.
Setting
California, USA, from 2002 to 2004.
Subjects
A total of 527 FSP female participants and 1405 potentially eligible non-participant females, aged 18 years and older.
Results
The following characteristics remained independently and positively related to FSP participation: single mother with children; unemployed; on welfare; on WIC (the Special Supplemental Nutrition Program for Women, Infants, and Children); and US-born. Women under 25 years and those over 54 years were less likely to participate than women aged 25–54 years. Hispanic/Latino ethnicity was also negatively related to participation. Over 42 % of potentially eligible non-participants cited ‘don’t need them’ as the reason for not applying for FSP, but 34·9 % either do not think they are eligible or do not know how to apply. Potentially eligible non-participants who cite ‘don’t need them’ as a reason for not applying are less likely to be food insecure, to have inadequate income and to use alternative emergency aid, compared to women citing all other reasons. The highest level of need is among those who cite worry about citizenship or stigma as reasons for not applying.
Conclusion
Strategies to increase participation in FSP should incorporate messages that change the public’s perception of the programme, in addition to simplifying the application process, raising awareness of eligibility criteria and improving customer service.
To assess the potential nutritional contribution of meals provided in a sample of community programmes for homeless individuals, to determine the effect of food donations on meal quality and to develop food-based guidance for meals that would meet adults’ total nutrient needs.
Setting
Toronto, Canada.
Design
An analysis of weighed meal records from eighteen programmes. The energy and nutrient contents of meals were compared to requirement estimates to assess contribution to total needs, given that homeless people have limited access to nutritious foods. Mixed linear modelling was applied to determine the relationship between the use of food donations and meal quality. The composition of meals that would meet adults’ nutrient requirements was determined by constructing simulated meals, drawing on the selection of foods available to programmes.
Sample
In all, seventy meals, sampled from eighteen programmes serving homeless individuals.
Results
On average, the meals contained 2·6 servings of grain products, 1·7 servings of meat and alternatives, 4·1 servings of vegetables and fruits and 0·4 servings of milk products. The energy and nutrient contents of most meals were below adults’ average daily requirements. Most meals included both purchased and donated foods; the vitamin C content of meals was positively associated with the percentage of energy from donations. Increasing portion sizes improved the nutrient contribution of meals, but the provision of more milk products and fruits and vegetables was required to meet adults’ nutrient requirements.
Conclusions
The meals assessed were inadequate to meet adults’ nutrient requirements. Improving the nutritional quality of meals requires additional resources.
To assess the nutritional status of Tunisian adolescents and associated factors.
Design
A cross-sectional study based on a national stratified random cluster sample.
Subjects and methods
In all, 1295 boys and 1577 girls aged 15–19 years, of whom 28·4 % had already left school. Socio-economic characteristics of the parents, anthropometric measurements, food behaviours and physical activity of the adolescents were recorded during home visits.
Results
Prevalence of underweight, overweight and obesity (WHO/National Center for Health Statistics reference) were, respectively, 8·1 %, 17·4 % and 4·1 % among boys and 1·3 %, 20·7 % and 4·4 % among girls; abdominal obesity was highly prevalent among both sexes. Prevalence of overweight differed by region (from 11·5 % to 22·2 %) and was higher in urban v. rural areas for males (21·7 % v. 10·4 %) but not for females (21·7 % v. 19·2 %). These differences were partially mediated by socio-economic and lifestyle factors for males. For females, influence of cultural factors is hypothesised. In rural areas, overweight was more prevalent among boys of higher economic level households, having a working mother or a sedentary lifestyle; for girls, prevalence increased with the level of education of the mother. In urban areas, prevalence of overweight was related to eating habits: it was higher for boys with irregular snacking habits and for girls skipping daily meals. Urban girls having left school were also more overweight.
Conclusion
Overweight and abdominal obesity in late adolescence have become a true public health problem in Tunisia with the combined effects of cultural tradition for girls in rural areas, and of rapid economic development for boys and girls in cities.
The progression from impaired glucose tolerance (IGT)/impaired fasting glucose (IFG) to type 2 diabetes can be prevented or delayed through intensive lifestyle changes. How to translate this to implementation across whole communities remains unclear. We now describe the results to a pilot of a personal trainer (Maori Community Health Worker, MCHW) approach among Maori in New Zealand.
Design, setting and subjects
A randomised cluster-controlled trial of intensive lifestyle change was commenced among 5240 non-pregnant Maori family members without diabetes from 106 rural and 106 urban geographical clusters. Baseline assessments included lifestyle questionnaires, anthropometric measurements and venesection. A pilot study (Vanguard Study) cohort of 160 participants were weighed before and during MCHW intervention, and compared with fifty-two participants weighed immediately before intervention and with 1143 participants from the same geographical area. Interactions between participants and the MCHW were reported using personal digital assistants with a programmed detailed structured approach to each interview.
Results
During the Vanguard Study, participants and MCHW found the messages, toolkit and delivery approach acceptable. Those with IGT/IFG diagnosed (n 27) experienced significant weight loss after screening and during the Vanguard Study (5·2 (sd 6·6) kg, paired t test P < 0·01). Significant weight loss occurred during the Vanguard Study among all participants (−1·3 (sd 3·6) kg, P < 0·001).
Conclusions
Comparable initial weight loss was shown among those with IGT/IFG and those from existing trials. Community-wide prevention programmes are feasible among Maori and are likely to result in significant reductions in the incidence of diabetes.
To investigate the prevalence of vitamin A deficiency (VAD) among pregnant women in rural Bangladesh, and examine the relationship between various factors and vitamin A status.
Setting
Community Nutrition Promoter (CNP) centres in Kapasia sub-district of Gazipur district, Bangladesh.
Design
A cross-sectional study.
Subjects and methods
Two hundred women, aged 18–39 years, in their second or third trimester of pregnancy were selected from seventeen CNP centres in four unions of Kapasia sub-district where they usually visit for antenatal care. Various socio-economic, personal and pregnancy-related information, dietary intake of vitamin A and mid-upper arm circumference (MUAC) data were collected. Serum retinol (vitamin A) concentration was determined.
Results
More than half (51 %) of the pregnant women had low vitamin A status (serum retinol <1·05 μmol/l) with 18·5 % having VAD (serum retinol <0·70 μmol/l). Fifty-three per cent of the women’s vitamin A intake was less than the recommended dietary allowance. By multiple regression analysis, MUAC, per-capita expenditure on food and wealth index were found to have significant independent positive relationship with serum retinol concentration, while gestational age of the pregnant women had a negative relationship. The overall F-ratio (10·3) was highly significant (P = 0·0001), the adjusted R2 was 0·18 (multiple R = 0·45).
Conclusion
VAD is highly prevalent among rural pregnant women in Bangladesh. Gestational age, nutritional status, per-capita expenditure on food and wealth index appear to be important in influencing the vitamin A status of these women. An appropriate intervention is warranted in order to improve the vitamin A status.
To evaluate body size preference, body weight perception and their relationship with actual weight in two migrant groups of non-Western origin, Turks and Moroccans; additionally, to study the association between body size preference and acculturation.
Design
Cross-sectional study.
Setting
Amsterdam, The Netherlands.
Subjects and methods
Males and females (18–30 years) were randomly selected from the population registry (n 451); participants, or at least one of their parents, were born in Turkey or Morocco. Body size preference was assessed using seven silhouette drawings and body weight perception was assessed by asking participants’ opinion of own weight. Acculturation variables were generation status and two scale measures, cultural orientation and social contacts.
Results
Participants showed preference for a thin body size. The discrepancy between ideal and current size was significant in women but not men (P < 0·001). Perceived current body size was correlated with BMI (Spearman’s correlation coefficient 0·60, P < 0·001 (men) and 0·73, P < 0·001 (women)). Among overweight participants (BMI = 25·0–29·9 kg/m2), 63–82 % of men and 35 % of women perceived themselves as ‘average’. Paying attention to own body weight was associated with a discrepancy between ideal and current size among women and with perceiving oneself as ‘overweight’ among men. Body size preference was not significantly associated with the three acculturation variables.
Conclusion
We did not observe a preference for large body sizes in these two non-Western migrant groups. Similar to Western populations, most women wished to be thinner than they were. This was not the case among men, the majority of whom were also unaware of being overweight.
The aims of the present work were to investigate whether dietary habits are associated with socio-economic status (SES), and if they modify the relationship between SES and CVD risk factors, in a sample of men and women free from known CVD.
Methods
This population-based study was carried out in the province of Attica, where Athens is a major metropolis. During 2001–2002, information from 1528 men (18–87 years old) and 1514 women (18–89 years old) was collected (75 % participation rate). Among several sociodemographic, clinical and biological factors, adherence to the Mediterranean diet was assessed by a special diet score (Mediterranean Diet Score, MDS) that incorporated the inherent characteristics of this traditional diet. CVD risk factors were examined across the participants’ educational level and annual income that defined their SES.
Results
Low SES groups exhibited higher prevalence of CVD risk factors, such as obesity, hypertension, diabetes mellitus and hypercholesterolaemia (all P < 0·001). Low SES groups also showed less adherence to the Mediterranean diet than high SES groups (MDS: 23·6 (sd 8·1) v. 25·6 (sd 5·6), P < 0·001). Higher SES index was associated with lower likelihood of having hypercholesterolaemia (OR = 0·91; 95 % CI 0·83, 1·00) and diabetes (OR = 0·83; 95 % CI 0·72, 0·95), after adjusting for various potential confounders. However, the previously mentioned inverse relationship observed between SES and prevalence of CVD risk factors was mainly explained by the dietary habits of the participants.
Conclusions
Low SES groups showed less adherence to the Mediterranean diet compared with high SES groups. This finding may, in part, explain the higher CVD risk factors profile observed among low SES participants.
Data on the prevalence and predictors of breast-feeding remain scarce in Lebanon. Moreover, no study has previously addressed the effect of the paediatrician’s sex on breast-feeding. The present study aimed to assess the prevalence and predictors of breast-feeding at 1 and 4 months of infant age while exploring the potential role of the sex of the paediatrician.
Design
Prospective cohort study. Predictors of breast-feeding significant at the bivariate level were tested at 1 and 4 months through two stepwise regression models.
Setting
Infants were enrolled through the clinics and dispensaries of 117 paediatricians located in Beirut, Lebanon, and its suburbs.
Subjects
A total of 1320 healthy newborn infants born between August 2001 and February 2002 were prospectively followed during the first year.
Findings
Breast-feeding rates at 1 and 4 months were 56·3 % and 24·7 %, respectively. Early discharge, high parity and religion were significantly associated with higher breast-feeding rates at 1 and 4 months of age. Maternal age proved significant only at 1 month, while maternal working status and sex of the paediatrician were significant at 4 months. A novel finding of our study was the positive effect of female paediatricians on breast-feeding continuation until 4 months of age (OR = 1·49; 95 % CI 1·03, 2·15).
Conclusions
Breast-feeding rates are low at 1 and 4 months of infant age in Beirut. Further research to investigate the interactions between female physicians and lactating mothers in maintaining breast-feeding in other populations is warranted. The results constitute the basis for designing interventions targeting policy makers, health professionals and mothers.
