Objectives: Preschool child undernutrition, reflected by high rates of stunting and wasting, remains endemic in rural South Asia. While prevention of early growth faltering is a public health priority, its etiology is poorly understood. Further, patterns remain depicted mostly through summaries of cross-sectional (survey) data. There is an ongoing need for the dynamics of growth to be better understood, assessed as velocity data by age, sex, locale and other factors, to inform and guide interventions. We assessed attained length/height and annual growth velocities over a period of three years in a representative cohort of children
Methods: This study was conducted from 2013-16 in a stratum of 21 assessed wards in 7 Village Development Committees (VDCs), representing the terai, among a national sample of 21 VDCs surveyed during the same season in 4 consecutive years in Nepal (PoSHAN Communities Study). Among an initial sub-set of 1333 children
Results: Mean (SD) attained HAZ decreased from -0.62 (1.45) nd year was -1.1 (4.0), and -0.32 (1.82) for children aging from 1 to 2 y. HAZ change for children 2, 3 and 4 y at the start of an interval was -0.03 (1.65), 0.13 (1.59) and 0.16 (1.19), respectively. Rates were also similar by sex. Annual linear growth velocities by month of age and sex annualized growth curves will be presented in further detail.
Conclusions: Nepali infants in the terai decelerate precipitously in attained HAZ growth, which becomes attenuated as children age from 2 to 3 years. Thereafter, children exhibit modest gains in HAZ against the WHO reference median, but still approach the school aged years markedly stunted.
