The dual burden household and the nutrition transition paradox

OBJECTIVE:The purpose of this study is to document the prevalence of households with underweight and overweight persons (henceforth referred to as dual burden households) and their association with income and urban residence. The explorations by urban residence and income will test whether dual burden households differ from ‘underweight only’ and ‘overweight only’ households, respectively. These comparisons are relevant to differentiating or adapting nutrition-related interventions wherever obesity and undernutrition cluster at the household level.POPULATION:Data analysis is based on national surveys conducted in Brazil, China, Indonesia, the Kyrgyz Republic, Russia, Vietnam and the United States.METHODS:All persons were first classified into categories for underweight and overweight, using body mass index (BMI) cutoffs, and then all households were categorized into four types: dual burden, overweight, underweight and normal. Income and urban residence were explored as key risk factors for being a dual burden household, with the effects modeled separately for each country. Multiple logistic regression was used to explore income and urban risk factors, controlling for household size, region of residence and either urban residence or income, as appropriate.RESULTS:In six of the countries studied, 22–66% of households with an underweight person also had an overweight person. Countries with the highest prevalence of dual burden households were those in the middle range of gross national product (GNP). The dual burden household is easily distinguished from the ‘underweight only’ households in Brazil, China, Indonesia, the United States and Vietnam. In these five countries dual burden households were more likely to be urban and more likely to be among the highest income tertile. There were no significant differences between dual burden and ‘underweight only’ households in Russia and the Kyrgyz Republic. In contrast, dual burden households were not easily distinguished from the ‘overweight only’ households in China, Indonesia, the Kyrgyz Republic, the United States and Vietnam. In Brazil and Russia dual burden households were more likely to be lower income and urban than ‘overweight only’ households.CONCLUSION:The prevalence of dual burden households presents a significant public health concern, particularly for those countries in the middle range of GNP. In some countries (China, Indonesia, the Kyrgyz Republic, the United States and Vietnam), dual burden households share sociodemographic profiles with overweight households, raising concerns for underweight individuals who may inadvertently become the focus of obesity prevention initiatives. For this reason, obesity prevention efforts should focus on messages that are beneficial to the good health of all, such as increasing fruit and vegetable intake, improving overall diet quality and increasing physical activity.

The Social Constructions of Sexuality: Marital Infidelity and Sexually Transmitted Disease–HIV Risk in a Mexican Migrant Community

OBJECTIVES This article explores the social context of the migration-related HIV epidemic in western Mexico. METHODS Data collection involved life histories and participant observation with migrant women in Atlanta and their sisters or sisters-in-law in Mexico. RESULTS Both younger and older women acknowledged that migrant mens sexual behavior may expose them to HIV and other sexually transmitted diseases.Younger Mexican women in both communities expressed a marital ideal characterized by mutual intimacy, communication, joint decisionmaking, and sexual pleasure, but not by willingness to use condoms as an HIV prevention strategy. CONCLUSIONS Migrant Mexican womens commitment to an illusion of fidelity will hinder HIV prevention initiatives targeted toward them. Furthermore, the changing meanings of marital sex may make it harder to convince young couples to use condoms as an HIV prevention strategy. If the chain of heterosexual marital HIV transmission is to be interrupted in this community, prevention programs must target men.

The burden of anemia among women in India

Objective: This research investigates the prevalence and determinants of anemia among women in Andhra Pradesh. We examined differences in anemia related to social class, urban/rural location and nutrition status body mass index (BMI). We hypothesized that rural women would have higher prevalence of anemia compared to urban women, particularly among the lower income groups, and that women with low body mass index (BMI; <18.5 kg/m2) would have a higher risk compared to normal or overweight women.Design: The National Family Health Survey 1998/99 (NFHS-2) provides nationally representative cross-sectional survey data on womens hemoglobin status, body weight, diet, social, demographic and other household and individual level factors. Ordered logit regression analyses were applied to identify socio-economic, regional and demographic determinants of anemia.Setting: Andhra Pradesh, a southern Indian state.Subjects: A total of 4032 ever-married women aged 15–49 from 3872 households.Results: Prevalence of anemia was high among all women. In all 32.4% of women had mild (100–109.99 g/l for pregnant women, 100–119.99 for non-pregnant women), 14.19% had moderate (70–99.99 g/l), and 2.2% had severe anemia (<70 g/l). Protective factors include Muslim religion, reported consumption of alcohol or pulses, and high socioeconomic status, particularly in urban areas. Poor urban women had the highest rates and odds of being anemic. Fifty-two percent of thin, 50% of normal BMI, and 41% of overweight women were anemic.Conclusion: New program strategies are needed, particularly those that improve the overall nutrition status of women of reproductive ages. This will require tailored programs across socio-economic groups and within both rural and urban areas, but particularly among the urban and rural poor.Sponsorship: Partial support for Margaret Bentley was provided by the Ford Foundation/India and the Carolina Population Center.

When HIV-Prevention Messages and Gender Norms Clash: The Impact of Domestic Violence on Women's HIV Risk in Slums of Chennai, India

This paper examines how marital violence affects womens ability to protect themselves from HIV/AIDS. In-depth interviews (n = 48) and focus groups (n = 84, 3–7 per group) were conducted among men and women in two randomly selected slums of Chennai, India. The study showed that community gender norms tacitly sanction domestic violence that interferes with adopting HIV-preventive behaviors. Given the choice between the immediate threat of violence and the relatively hypothetical specter of HIV, women often resign themselves to sexual demands and indiscretions that may increase their risk of HIV acquisition. In conclusion, AIDS-prevention interventions must incorporate gender-related social contexts in settings where husbands strictly enforce their locus of control. HIV-prevention messages targeting men may effectively reduce womens exposure to HIV/AIDS.

WIC-Based Interventions to Promote Breastfeeding Among African-American Women in Baltimore: Effects on Breastfeeding Initiation and Continuation

We evaluated the single and combined effects of introducing a motivational video and peer counseling into four matched WIC clinics on breastfeeding initiation and continuation at 7-10 days among African-American WIC participants. Of the 242 women with complete data, 48% initiated breastfeeding, but only 31% were still breastfeeding at 7-10 days. Initiation was associated with cesarean delivery, infant feeding instruction, no artificial milk discharge pack, attending the peer counselor only-intervention site, and intention to breastfeed. Continuation was influenced by infant feeding instruction, no artificial milk discharge pack, and intention to breastfeed. Overall, trends toward a positive impact of the breastfeeding promotion activities were evident but weak, and largely gone by 7-10 days postpartum.

Rapid ethnographic assessment: Applications in a diarrhea management program

This paper reports on a rapid ethnographic assessment methodology (REA) that was developed as an essential component of the dietary management of diarrhea (DMD) program. The DMD program is an interdisciplinary research project that has been developed to design intervention programs to reduce or eliminate the nutritional complications of diarrhea in Peru and Nigeria. Anthropological data gathering was an important component of the intervention design, but time and budgetary constraints required a rapid methodological approach. This paper outlines the REA methodology, describes the advantages and disadvantages of the approach, and discusses future applications for international primary health care interventions.

The role of care in nutrition programmes: current research and a research agenda

The importance of cultural and behavioural factors in childrens nutrition, particularly with regard to feeding, has been recognized only recently. The combination of evidence regarding the importance of caregiving behaviour for good nutrition, and improved strategies for measuring behaviour have led to a renewed interest in care. The UNICEF conceptual framework suggests that care, in addition to food security and health care services, are critical for childrens survival, growth and development. The present paper focuses on the care practice of complementary feeding, specifically behavioural factors such as parental interaction patterns, feeding style and adaptation of feeding to the childs motor abilities (self-feeding or feeding by others). Three kinds of feeding styles (Birch & Fisher, 1995) are identified: controlling; laissez-faire; responsive. Probable effects of each feeding style on nutrient intake are described. A number of studies of feeding behaviour have suggested that the laissez-faire style is most frequently observed among families and communities with a higher prevalence of malnourished children. Nutrition interventions that have been able to show significant effects on outcomes, such as the Hearth Model in Vietnam (Sternin et al. 1997), have usually incorporated behavioural components in their intervention. At this time, there have been no tests of the efficacy of behavioural interventions to improve feeding practices. Research is needed to understand behavioural factors in complementary feeding, and to identify and test intervention strategies designed to improve nutrient intake of young children. Finally, the paper concludes with a discussion of how nutrition programmes might change if care were incorporated.

Delaying second births among adolescent mothers: a randomized, controlled trial of a home-based mentoring program.

CONTEXT. Rates of rapid second births among low-income black adolescent mothers range from 20% to 50%. Most efforts to prevent rapid second births have been unsuccessful. OBJECTIVES. There were 4 objectives: (1) to examine whether a home-based mentoring intervention was effective in preventing second births within 2 years of the adolescent mothers first delivery; (2) to examine whether greater intervention participation increased the likelihood of preventing a second birth; (3) to examine whether second births were better predicted from a risk practice perspective or a family formation perspective, based on information collected at delivery; and (4) to examine how risk practices or family formation over the first 2 years of parenthood were related to a second birth. DESIGN. We conducted a randomized, controlled trial of a home-based intervention curriculum, based on social cognitive theory, and focused on interpersonal negotiation skills, adolescent development, and parenting. The curriculum was delivered biweekly until the infants first birthday by college-educated, black, single mothers who served as mentors, presenting themselves as “big sisters.” The control group received usual care. Follow-up evaluations were conducted in the homes 6, 13, and 24 months after recruitment. METHODS. Participants were recruited from urban hospitals at delivery and were 181 first time, black adolescent mothers (<18 years of age); 82% (149 of 181) completed the 24-month evaluation. RESULTS. Intent-to-treat analyses revealed that control mothers were more likely than intervention mothers to have a second infant. The complier average causal effect was used to account for variability in intervention participation. Having ≥2 intervention visits increased the odds of not having a second infant more than threefold. Only 1 mother who completed ≥6 visits had a second infant. At delivery of their first infant, mothers who had a second infant were slightly older (16.7 vs 16.2 years) and were more likely to have been arrested (30% vs 14%). There were no differences in baseline contraceptive use or other measures of risk or family formation. At 24 months, mothers who had a second infant reported high self-esteem, positive life events, and romantic involvement and residence with the first infants father. At 24 months, there were no differences in marital rates (2%), risk practices, or contraceptive use between mothers who did and did not have a second infant. Mothers who did not have a second infant were marginally more likely to report no plans for contraception in their next sexual contact compared with mothers who had a second infant (22% vs 8%, respectively). CONCLUSIONS. A home-based intervention founded on a mentorship model and targeted toward adolescent development, including negotiation skills, was effective in preventing rapid repeat births among low-income, black adolescent mothers. The effectiveness of the intervention could be seen after only 2 visits and increased over time. There were no second births among mothers who attended ≥8 sessions. There was no evidence that risk behavior or contraceptive use was related to rapid second births. There was some evidence that rapid second births among adolescent mothers were regarded as desirable and as part of a move toward increasing autonomy and family formation, thereby undermining intervention programs that focus on risk avoidance. Findings suggest the merits of a mentoring program for low-income, black adolescent mothers, based on a relatively brief (6–8 sessions) curriculum targeted toward adolescent development and interpersonal negotiation skills.

Safety and Tolerability of BufferGel, a Novel Vaginal Microbicide, in Women in the United States

BufferGel (ReProtect, LLC) is a vaginal gel with an acidic buffering action that was designed to prevent vaginal neutralization by semen. The purpose of this study was to evaluate the safety and tolerability of BufferGel (ReProtect, Limited Liability Company) applied vaginally either once or twice daily by 27 women who were at low risk for acquisition of human immunodeficiency virus (HIV). Participants initially used the product once daily for 14 days and then twice daily for 14 days; they underwent colposcopy before and after product exposure. BufferGel was well tolerated, although two-thirds of the participants reported at least 1 mild or moderate adverse experience. The most common adverse events were irritative genitourinary symptoms. Product use was discontinued after 3 adverse events. BufferGel was well tolerated in women at low risk for acquisition of HIV; toxicity was limited and occurred at frequencies similar to those in women who did not use any vaginal product and at levels lower than in women who used detergent-based microbicides.

Cluster‐randomized trial on complementary and responsive feeding education to caregivers found improved dietary intake, growth and development among rural Indian toddlers

Inadequate feeding and care may contribute to high rates of stunting and underweight among children in rural families in India. This cluster-randomized trial tested the hypothesis that teaching caregivers appropriate complementary feeding and strategies for how to feed and play responsively through home-visits would increase childrens dietary intake, growth and development compared with home-visit-complementary feeding education alone or routine care. Sixty villages in Andhra Pradesh were randomized into three groups of 20 villages with 200 mother-infant dyads in each group. The control group (CG) received routine Integrated Child Development Services (ICDS); the complementary feeding group (CFG) received the ICDS plus the World Health Organization recommendations on breastfeeding and complementary foods; and the responsive complementary feeding and play group (RCF&PG) received the same intervention as the CFG plus skills for responsive feeding and psychosocial stimulation. Both intervention groups received bi-weekly visits by trained village women. The groups did not differ at 3 months on socioeconomic status, maternal and child nutritional indices, and maternal depression. After controlling for potential confounding factors using the mixed models approach, the 12-month intervention to the CFG and RCF&PG significantly (P < 0.05) increased median intakes of energy, protein, Vitamin A, calcium (CFG), iron and zinc, reduced stunting [0.19, confidence interval (CI): 0.0-0.4] in the CFG (but not RCF&PG) and increased (P < 0.01) Bayley Mental Development scores (mean = 3.1, CI: 0.8-5.3) in the RCF&PG (but not CFG) compared with CG. Community-based educational interventions can improve dietary intake, length (CFG) and mental development (RCF&PG) for children under 2 years in food-secure rural Indian families.
