Seasonal variation in the proximal determinants of undernutrition during the first 1000 days of life in rural South Asia: A comprehensive review
In this review, the inﬂuence of seasonal variation on under nutrition during the ﬁrst 1000 days of life of life in rural South Asia is conceptualized using a modiﬁed framework developed under the “Tackling the Agriculture and Nutrition Disconnect in India” project. Evidence for the existence and extent of seasonality is summarized from 14 studies reporting on six proximal determinants of under nutrition. A limited number of studies examine seasonal variation in risk factors for this age group. All available studies, however, report a compelling ﬁnding of signiﬁcant seasonal variation for at least one determinant of under nutrition. Research to clarify mechanisms for potentially adverse eﬀects of seasonal variation on health and nutritional status during the ﬁrst 1000 days of life is needed.
