Maternal Antiretroviral Therapy Is Associated with Lower Risk of Diarrhea in Early Childhood.

ABSTRACT: OBJECTIVES:To identify risk factors, including maternal antiretroviral therapy (ART), for diarrhea in Tanzanian children exposed to HIV during the first 2 years of life. STUDY DESIGN:Using generalized estimating equations, we analyzed data from a cohort of 2387 Tanzanian children exposed to HIV from age 6 weeks to 2 years, as well as data from their mothers, to determine risk factors for diarrhea in children. Mothers recorded diarrhea in a diary and reported results at visits scheduled every four weeks. RESULTS:Body mass index was ?18.5 in 95.6% of mothers. World Health Organization HIV stage was 1/2 for 1255 (87.8%) mothers. ART was received by 24.3% of mothers, most initiating ART during pregnancy. At baseline (6 weeks of age) 264 (11.3%) children were infected with HIV. In children whose mothers received ART, the relative risk of diarrhea in children was 0.79 (95% CI 0.68-0.92), after we adjusted for multiple factors, including child HIV status and exclusive breastfeeding duration. Exclusive breastfeeding (relative risk 0.67, 95% CI 0.56-0.80) also was protective. CONCLUSION:Our results provide additional support to increase ART coverage for all pregnant mothers, to control clinical HIV progression, reduce perinatal HIV infection, but also to reduce the risk of a major cause of death and morbidity in young children worldwide. TRIAL REGISTRATION:ClinicalTrials.gov: NCT00197730.

Project description:BackgroundThe World Health Organization recommends 20 mg of zinc per day for 10 to 14 days for children with acute diarrhea; in previous trials, this dosage decreased diarrhea but increased vomiting.MethodsWe randomly assigned 4500 children in India and Tanzania who were 6 to 59 months of age and had acute diarrhea to receive 5 mg, 10 mg, or 20 mg of zinc sulfate for 14 days. The three primary outcomes were a diarrhea duration of more than 5 days and the number of stools (assessed in a noninferiority analysis) and the occurrence of vomiting (assessed in a superiority analysis) within 30 minutes after zinc administration.ResultsThe percentage of children with diarrhea for more than 5 days was 6.5% in the 20-mg group, 7.7% in the 10-mg group, and 7.2% in the 5-mg group. The difference between the 20-mg and 10-mg groups was 1.2 percentage points (upper boundary of the 98.75% confidence interval [CI], 3.3), and that between the 20-mg and 5-mg groups was 0.7 percentage points (upper boundary of the 98.75% CI, 2.8), both of which were below the noninferiority margin of 4 percentage points. The mean number of diarrheal stools was 10.7 in the 20-mg group, 10.9 in the 10-mg group, and 10.8 in 5-mg group. The difference between the 20-mg and 10-mg groups was 0.3 stools (upper boundary of the 98.75% CI, 1.0), and that between the 20-mg and 5-mg groups was 0.1 stools (upper boundary of the 98.75% CI, 0.8), both of which were below the noninferiority margin (2 stools). Vomiting within 30 minutes after administration occurred in 19.3%, 15.6%, and 13.7% of the patients in the 20-mg, 10-mg, and 5-mg groups, respectively; the risk was significantly lower in the 10-mg group than in the 20-mg group (relative risk, 0.81; 97.5% CI, 0.67 to 0.96) and in the 5-mg group than in the 20-mg group (relative risk, 0.71; 97.5% CI, 0.59 to 0.86). Lower doses were also associated with less vomiting beyond 30 minutes after administration.ConclusionsLower doses of zinc had noninferior efficacy for the treatment of diarrhea in children and were associated with less vomiting than the standard 20-mg dose.

Project description:The objective of this investigation was to describe maternal psychosocial, behavioral, and acculturation factors associated with early childhood caries in a sample of urban Latino mother-child dyads. A cross-sectional survey was conducted with 100 mothers whose children (under the age of 6 y) were patients at the Dental Center at Children's Hospital Colorado in Aurora, Colorado. All children participating in the study received an oral examination to measure decayed, missing, filled, surfaces (dmfs). Participating mothers were given the option to sign the consent form and complete the survey in English or Spanish, according to their preferred language. The survey used demographic, behavioral, knowledge, and several psychosocial variables. Bivariate analysis was conducted with dmfs as a dependent variable. The associations between independent variables and dmfs were modeled using negative binomial regression. Mean ± SD dmfs for the entire sample was about 11 ± 16.85. The mothers who spoke Spanish had children with significantly (P = 0.046) higher dmfs scores (15.2) compared to mothers who spoke English (7.56). Preference of Spanish language was significantly associated with self-efficacy (P = 0.0043), oral health knowledge (P = 0.0024), and 3 subscales of the health belief model: perceived severity (P = 0.057), perceived barriers (P = 0.0002), and perceived susceptibility (P = 0.008). Both in the univariate and the multivariate models, oral health behavior and preferential use of Spanish remained significantly associated with higher dmfs scores. Results of this study demonstrate that maternal oral health behaviors and preferred language are significant factors associated with early childhood caries in urban Latino children. Knowledge Transfer Statement: Results of this study indicate that maternal oral health behaviors and the level of acculturation are significantly associated with caries in urban Latino children. Caries prevention efforts in this population could use this information to tailor oral health messaging according to the level of acculturation in mothers.

Project description:Diarrhea and linear growth faltering continue to burden low-income countries and are among the most important contributors to poor health during early childhood. Diarrhea is thought to adversely affect linear growth, but catch-up growth can occur if no additional insults are experienced. We sought to characterize catch-up growth in relation to diarrhea burden in a multisite dataset of 1007 children. Using longitudinal anthropometry and diarrheal surveillance data from 7 cohort studies in 4 countries, we examined the relation between diarrhea prevalence and growth in 3- to 6-mo periods using linear mixed-effect models. Growth during each period was calculated as a function of age using linear splines. We incorporated the longitudinal prevalence of diarrhea in both current and previous periods into the model. Diarrhea during the current period was associated with slower linear and ponderal growth. Faster (catch-up) growth in length was observed in children with no diarrhea in age groups immediately after an age group in which diarrhea was experienced [age group >6-12 mo: 0.03 mm/mo for each percentage diarrhea prevalence in the previous period (95% CI: 0.007, 0.06) relative to 11.3 mm/mo mean growth rate; age group >12-18 mo: 0.04 mm/mo (95% CI: 0.02, 0.06) relative to 8.9 mm/mo mean growth rate; age group >18-24 mo: 0.04 mm/mo (95% CI: 0.003, 0.09) relative to 7.9 mm/mo mean growth rate]. The associations were stronger in boys than in girls when separate models were run. Similar results were observed when weight was the outcome variable. When diarrheal episodes are followed by diarrhea-free periods in the first 2 y of life, catch-up growth is observed that may allow children to regain their original trajectories. The finding of a greater effect of diarrhea on linear growth in boys than in girls was unexpected and requires additional study. Diarrhea burdens are high throughout the first 2 y of life in these study sites, therefore reducing the likelihood of catch-up growth. Extending diarrhea-free periods may increase the likelihood of catch-up growth and decrease the prevalence of stunting.
