ABSTRACT
OBJECTIVES: Nutrition has profound effects on children's health outcomes and is linked to weight gain and cognitive development. We used data from a randomised controlled trial to evaluate the prospective associations between dietary, socioeconomic and demographic factors and short-term weight gain during the lean season in a rural area of Burkina Faso. DESIGN: Prospective cohort data arising from a randomised controlled trial of the effect of antibiotic distribution on child growth and intestinal microbial diversity. SETTING: Two rural communities in Nouna District, Burkina Faso. PARTICIPANTS: 246 children aged 6-59 months living in the study communities were enrolled in the study. PRIMARY AND SECONDARY OUTCOME MEASURES: Anthropometric measurements, including weight and height, were obtained at baseline and 1 month. RESULTS: Of 246 children, the median weight for wasted children at baseline (weight-for-height z-score <-2) was 9.7 kg (IQR 8.65-10.8) and the weight of non-wasted children was 12.8 kg (IQR 10.9-14.75). Food insecurity was significantly associated with decreased weight gain velocity (mean difference -0.03 g/kg/day, 95% CI -0.06 to -0.006, p=0.04). CONCLUSION: Experiences of household food insecurity before the beginning of the lean season were associated with decreased weight gain in children in rural Burkina Faso during the lean season, although the mean difference was small. Understanding the relationship between timing of food insecurity and anthropometric outcomes may help to develop policies and health programme that address both of these issues. TRIAL REGISTRATION NUMBER: NCT03187834.

Mass azithromycin distribution is a core component of trachoma control programmes and could reduce mortality in children younger than 5 years in some settings. In this systematic review we synthesise evidence on the emergence of antimicrobial resistance after mass azithromycin distribution. We searched electronic databases for publications up to June 14, 2018. We included studies of any type (excluding modelling studies, surveillance reports, and review articles) on community-wide distribution of oral azithromycin for the prevention and treatment of trachoma that assessed macrolide resistance, without restrictions to the type of organism. We extracted prevalence of resistance from published reports and requested unpublished data from authors of included studies. Of 213 identified studies, 19 met inclusion criteria (12 assessed Streptococcus pneumoniae) and were used for qualitative synthesis. Macrolide resistance after azithromycin distribution was reported in three of the five organisms studied. The lack of resistance in Chlamydia trachomatis suggests that azithromycin might remain effective for trachoma programmes, but evidence is scarce. As mass azithromycin distribution for trachoma continues and is considered for other indications, ongoing monitoring of antimicrobial resistance will be required.
