Study Rationale
As the double burden of nutrition emerges in Bangladesh and other low- to middle-income countries, it is imperative to develop strategies to mitigate the adverse effects associated with both undernutrition and obesity. Identifying levels of physical activity among children is a requisite step to developing and targeting interventions to promote physical activity among young populations. Furthermore, exploring the risk factors associated with physical activity levels in young children can help better inform policy makers surrounding a public health intervention.
Goals The overall goal of the research is to generate new knowledge regarding the nutritional and environmental determinants of physical activity in young children living in a densely populated urban community in Bangladesh.
Primary Objectives
The specific objectives of this study are to:
- Describe physical activity levels in a sample of preschool-aged children in an inner-city community in Dhaka, Bangladesh,
- Estimate the associations between characteristics of the physical environment of the home (total area of available floor space inside of the home, number and presence of physical hazards, and the number of gross motor activity-oriented items present) and the physical activity levels of preschoolers in Dhaka, and
- Estimate the associations between hemoglobin concentration (Hb) and preschooler physical activity level.
- Describe sleep quantity and quality in the sample of preschool-aged children in urban Bangladesh
The investigators conducted a cross-sectional observational study of preschool-aged children between 34-38 months of age (n=60) selected from the ongoing Maternal Vitamin D for Infant Growth (MDIG) trial cohort (NCT01924013) in Dhaka, Bangladesh. The investigators planned to enrol a minimum of 60 participants with complete data sets, with recruitment up to 90 participants until this enrolment target was reached.
Study Procedures

Objectively measured accelerometry data, a continuous variable reflecting mean daily PA during the study period, expressed as mean counts per 15 seconds (cp15s).
This summary measure was generated by first calculating mean daily PA, then averaging the daily means across collection days, including data between the time the child woke up until the time the child went to sleep, as reported by the caregiver on all days that met criteria for inclusion (i.e., at least 10 hours of wear time)
