Household food security is inversely associated with undernutrition among adolescents from Kilosa, Tanzania.

Household food insecurity contributes to poor nutritional health, with negative consequences on growth and development during childhood. Although early childhood nutrition needs have received much attention, another important nutritional phase is adolescence. In a sample of 670 adolescents from Kilosa District, Tanzania, this study used 3 approaches to better understand the relationship between food insecurity and undernutrition. First, this study examined the associations between 3 commonly used measures of household food security and undernutrition among 670 adolescents from Kilosa District, Tanzania. The measures of household food security, energy adequacy per adult equivalent, dietary diversity score, and coping strategies index, were strongly correlated with each other and household assets (P < 0.05). Second, this study measured the nutritional status of adolescents in this district, finding a high prevalence of undernutrition (21% with BMI-for-age <5th percentile of the National Center for Health Statistics/WHO reference). Third, this study measured the association between the log odds of undernutrition (as the dependent variable) and each of the 3 measures of household food security. In separate models, household energy adequacy per adult equivalent and household dietary diversity score were inversely associated with undernutrition after adjusting for gender, age, puberty, and the interaction between age and puberty. By contrast, a greater use of coping strategies was not associated with undernutrition. Strategies focused on increasing household energy intake and improving dietary diversity among the most vulnerable households could improve the nutritional health of adolescents.

Community-level micronutrient fortification of a food supplement in India: a controlled trial in preschool children aged 36-66 mo.

BACKGROUND: Children participating in the Integrated Child Development Service (ICDS) in India have high rates of iron and vitamin A deficiency. OBJECTIVE: The objective was to assess the efficacy of a premix fortified with iron and vitamin A and added at the community level to prepared khichdi, a rice and dal mixture, in increasing iron and vitamin A stores and decreasing the prevalence of iron deficiency, anemia, and vitamin A deficiency. DESIGN: This cluster, randomized, double-blind, controlled trial was initiated in 30 Anganwadi centers (daycare centers) in West Bengal state, India. Children aged 36-66 mo (n = 516) attending village-based ICDS centers were randomly assigned to receive either a fortified or a nonfortified premix for 24 wk. Blood was drawn at 0 and 24 wk by venipuncture for the measurement of hemoglobin, serum ferritin, and serum retinol. RESULTS: The change in the hemoglobin concentration of anemic children was significantly different between fortified and nonfortified khichdi groups (P < 0.001). Prevalence rates of anemia, iron deficiency, and iron deficiency anemia were significantly lower after 24 wk in the fortified-khichdi group than in the nonfortified-khichdi group (P < 0.001). There were no significant differences in serum retinol concentrations or in the prevalence of vitamin A deficiency between the fortified- and nonfortified-khichdi groups. CONCLUSION: A premix fortified with iron, vitamin A, and folic acid and added to supplementary food at the community level can be effective at increasing iron stores and reducing the prevalence of iron deficiency and anemia.

Utilization of positive deviance analysis in evaluating community-based nutrition programs: an application to the Dular program in Bihar, India.

BACKGROUND: Positive deviance is increasingly employed in international development activities to permit the utilization of proven local solutions. Including positive deviance methods in evaluation analysis, particularly in places like Bihar, India, where the rates of child underweight hover at 55%, can help identify project activities and household characteristics that affect key outcomes. These can, in turn, inform decision-making regarding the intensification of particularly promising activities. OBJECTIVES: To apply positive deviance analysis to the Dular program in Bihar, a community-based nutrition program that seeks to improve the impact of India's Integrated Child Development Services on young children. METHODS: In order to assure that desired program outcomes were not dependent on higher economic status, the analysis isolated a subset of program beneficiaries--the poorest children with the best nutritional outcomes--and examined the behavioral and project factors that may have brought about positive results in this subgroup. The data for this analysis were drawn from a 2005 program evaluation with a sample of 1,560 children. RESULTS: The analysis found that positive deviant children with normal nutritional status in the poorest 50% of Dular households were introduced to complementary food almost 2 months earlier (7.18 vs. 9.02 months of age) than severely malnourished children, were more than twice as likely to use soap for handwashing after defecation (25.0% vs. 11.8%), and were more than seven times as likely to have literate mothers (25.0% vs. 3.5%). CONCLUSIONS: The analysis suggests that programmatic efforts relating to these activities have been particularly effective and may well deserve increased investment.

A positive deviance-based antenatal nutrition project improves birth-weight in Upper Egypt.

The positive deviance approach identifies and promotes existing uncommon healthy behaviours. A positive deviance-informed antenatal project was pilot-tested in Al-Minia Governorate, Upper Egypt, during 2003-2004, after a positive deviance study in 2000 found that successful pregnancies had increased consumption of meat and vegetables, daytime rest, and antenatal care; less second-hand smoke exposure; and symptoms of no urinary tract infection. Accordingly, health facilities were upgraded in target and comparison areas to provide quality antenatal care, including treatment of urinary tract infection. Additionally, in the target villages, women at-risk of delivering low-birth-weight infants were enrolled in weekly 'IMPRESS' (improved pregnancy through education and supplementation) sessions with counselling and supplemental food. In total, 519 women (344 target, 175 comparison) were enrolled in the third or fourth month of pregnancy and were followed through delivery. Birth-weights of the target mothers increased 2.2 times more than birth-weights of the comparison mothers over baseline (mean increase: 0.58 vs 0.26 g respectively, p<0.01). Similarly, the decrease in prevalence of low birth-weight from baseline was greater in the target villages than in the comparison mothers (% of decrease: 26.9 vs 11.9 respectively, p<0.01). The target at-risk women were far more likely than their counterparts to report eating more food (54.9% vs 10.6%), more meat (57.1% vs 4.2%), more vegetables (66.9% vs 5.3%), increasing daytime rest (64.1% vs 11.7%), and avoiding second-hand smoke (91.3% vs 51.6%) during pregnancy. The cost per 100 g of improvement in birth-weight was US$ 3.98. The Government of Egypt and partners are scaling up the elements of the project.

Effect of targeted food supplementation and services in the Bangladesh Integrated Nutrition Project on women and their pregnancy outcomes.

Monitoring data from the Bangladesh Integrated Nutrition Project and new data collected for this purpose were analyzed to assess the effects of targeted project services, including supplementation of food, on malnourished pregnant women (women with a body mass index [BMI] of < or = 18.5 in early pregnancy). Monitoring data on 456 women--195 receiving food supplement and 261 not receiving supplement--were collected from 17 upazilas (sub-districts) in four districts of Bangladesh. The assessment found that, despite lower economic status, the women with low BMI receiving supplementation of food and intensified services were more likely to have adequate pregnancy-related weight gain than the more economically-advantaged women with higher BMI. Primigravidae receiving supplementation were also more likely to have adequate pregnancy-related weight gain than the better-off non-supplemented primigravidae (85.7% vs 51.9%, p = 0.044). The mean birth-weights of infants of the supplemented women with low BMI were comparable to those of the better-off, non-supplemented women.

Morinda revisited: changes in nutritional well-being and gender differences after 30 years of rapid economic growth in rural Punjab, India.

A follow-up study of malnutrition and its determinants among children 6 to 24 months of age was carried out in rural areas of Punjab State in India 30 years after the original study, and following a period of rapid economic growth. The original 1971 study had found a high prevalence of mortality and malnutrition and the worst gender difference in nutritional status ever recorded in an Indian study. The 2001 follow-up study found dramatic reductions in child mortality, child malnutrition, gender-based imbalances in child well-being and care, and family size, the result of participatory economic growth coupled with broad-based educational, health, and family-planning services. Despite overall improvements in caloric intake, however, 40% of lower-class children in 2001 were still consuming less than 50% of their caloric allowance. With minimal gender-based abortion and significantly reduced neglect and mortality offemale children, gender balance among children in this area of rural Punjab improved markedly over the 30-year period.

Factors associated with successful pregnancy outcomes in upper Egypt: a positive deviance inquiry.

A positive deviance inquiry was conducted in Al-Minia, Upper Egypt, to identify factors associated with achievement of good pregnancy outcomes despite limited resources. As compared with women with poor weight gain (n = 30), low-income women with weight gain greater than 1.5 kg per month in the second trimester of pregnancy (n = 11) were more likely to report multiple antenatal care contacts (80% versus 43%), increased rest during pregnancy (67% versus 7%), and more consumption of meat (33% versus 13%) and vegetables (82% versus 37%), and were less likely to report symptoms consistent with urinary tract infection (50% versus 90% with dysuria and 0% versus 57% with cloudy or reddish urine). Similar characteristics distinguished low-income women in a more economically advantaged community whose newborns weighed more than 3 kg (n = 18) as compared with mothers of smaller newborns (n = 18). These characteristics were similar to those identified in the National Research Center's Al-Minia birthweight study. The positive deviance inquiry is an affordable, participatory step to identify accessible individuals, behaviors, and conditions for improved perinatal health.
