Short sleep duration and childhood obesity: cross-sectional analysis in Peru and patterns in four developing countries.

ABSTRACT:

Background

We aimed to describe the patterns of nutritional status and sleep duration in children from Ethiopia, India, Peru and Vietnam; to assess the association between short sleep duration and overweight and obesity, and if this was similar among boys and girls in Peru.

Methods and findings

Analysis of the Young Lives Study, younger cohort, third round. In Ethiopia there were 1,999 observations, 2,011, 2,052 and 2,000 in India, Peru and Vietnam, respectively. Analyses included participants with complete data for sleep duration, BMI, sex and age; missing data: 5.9% (Ethiopia), 4.1% (India), 6.0% (Peru) and 4.5% (Vietnam). Exposure was sleep duration per day: short (<10 hours) versus regular (10-11 hours). Outcome was overweight and obesity. Multivariable analyses were conducted using a hierarchical approach to assess the effect of variables at different levels. Overweight/obesity prevalence was 0.5%/0.2% (Ethiopia), 1.3%/0.3% (India), 6.1%/2.8% (Vietnam), and 15.8%/5.4% (Peru). Only Peruvian data was considered to explore the association between short sleep duration and overweight and obesity, with 1,929 children, aged 7.9±0.3 years, 50.3% boys. Short and regular sleep duration was 41.6% and 55.6%, respectively. Multivariable models showed that obesity was 64% more prevalent among children with short sleep duration, an estimate that lost significance after controlling for individual- and family-related variables (PR: 1.15; 95%CI: 0.81-1.64). Gender was an effect modifier of the association between short sleep duration and overweight (p?=?0.030) but not obesity (p?=?0.533): the prevalence ratio was greater than one across all the models for boys, yet it was less than one for girls.

Conclusions

Childhood overweight and obesity have different profiles across developing settings. In a sample of children living in resource-limited settings in Peru there is no association between short sleep duration and obesity; the crude association was slightly attenuated by children-related variables but strongly diminished by family-related variables.

Project description:BackgroundChildhood obesity is an urgent worldwide concern associated with increased morbidity in adulthood. Healthcare professionals (HCPs) are well placed to influence childhood obesity trends and implement interventions. English-language studies regarding HCPs' perceptions of childhood obesity are limited to high-income countries. Peru is an upper-middle-income country with regional disparities in childhood obesity prevalence. This qualitative study aims to explore HCPs' perceptions of childhood obesity in Iquitos, Peru, where prevalence is relatively low.MethodsTwenty-one HCPs with child healthcare experience were purposively recruited from two primary healthcare centres. Semi-structured, individual interviews were conducted with a translator and audio recorded. Transcribed data were analysed using thematic analysis.ResultsEight themes were identified and divided into four categories: (1) HCPs' perceptions and attitudes towards childhood obesity (level of concern regarding childhood obesity, perceived consequences of childhood obesity); (2) Factors which HCPs perceive to be important in the development of childhood obesity (parental factors, contextual factors); (3) HCPs' perceptions of their role in childhood obesity prevention and management (educating parents about childhood obesity, regular monitoring of child growth); and (4) Barriers and facilitators in childhood obesity prevention and management (in healthcare, in schools).ConclusionsHCPs had a low level of concern regarding childhood obesity in Iquitos and prioritised undernutrition. Parental factors were perceived to be the most influential in the development of childhood obesity. HCPs perceived themselves to have minimal influence due to prevailing positive views of excess weight and difficulties engaging parents. Educating parents about childhood obesity was felt to be essential to prevention and management although regular monitoring of child growth and home healthcare visits were viewed as useful additional measures. This study can help to inform the development of targeted public health strategies which are sensitive to local contexts and could prevent the upward childhood obesity trends evident elsewhere in Peru.
