Trends and factors associated with the nutritional status of adolescent girls in Ghana: a secondary analysis of the 2003–2014 Ghana demographic and health survey (GDHS) data

Abstract

Objective: We examined the trends-over-time and the factors associated with malnutrition among adolescent girls in Ghana. Design: Cross-sectional analysis from 3 nationwide Ghana Demographic and Health Surveys conducted in 2003 (n=983), 2008 (n=955) and 2014 (n=857). We used Cox proportional hazard models with sample weighting to model the prevalence ratio (PR) of malnutrition. Setting: Countrywide, covering rural and urban areas in Ghana. Subjects: Non-pregnant adolescents girls aged 15-19 years. Results: Compared with 2003, thinness declined marginally [PR 0.88 95% C.I (0.45, 1.73)] in 2008 and in 2014 [PR 0.71 95% C.I (0.38, 1.56)]. Stunting declined marginally by 19% in 2008 [PR 0.81 95% C.I (0.59, 1.12)], flattening out in 2014 [PR 0.81 95% C.I (0.57, 1.17)]. We found an increasing trend of overweight/obesity with the PR peaking in 2014 [PR 1.39 95% C. I (1.02, 1.88)] compared to 2003. The anaemia prevalence remained severe without a clear trend. A low level of education of the adolescent girl was positively associated with stunting. Increasing age was positively associated with stunting but inversely associated with thinness and anaemia. Girls who ever bore a child were more likely to be anaemic compared to those who never did. A lower level of household wealth and a unit increase in household size were negatively associated with overweight/obesity. Urban dwelling girls were less likely to be stunted. Conclusion: The stagnant burden of undernutrition and rising overnutrition emphasise the need for double-duty actions to tackle malnutrition in all its forms in Ghanaian adolescent girls.

Undernutrition and anaemia among Indian adolescents: role of dietary diversity and hygiene practices

“…Malnutrition is a complex phenomenon characterised by a multiplicity of factors ranging from the socioeconomic status to dietary intake, water, sanitation and hygiene (WASH) practices, and socio-political factors affecting policymaking (3)(4)(5) . Addressing the adolescent nutrition is fundamental to materialise the potential human capital gains and to break the intergenerational malnutrition trap.…”

The magnitude of stunting and its determinants among late adolescent girls in East Africa: Multilevel binary logistics regression analysis

“…Explanatory variables were classified as individual and community-level factors. Explanatory variables were Socioeconomic, demographic, and Environmental factors were selected based on previous studies and their availability in the DHS dataset [21][22][23][24][25]. Individual level variables considered in this study were age, marital status, educational status, sex of head, number of under-five, current working status, breastfeeding, religion, relationship to head, age of household head, wealth index, source of drinking water, time to get to a water source, and latrine.…”

Women’s health: optimal nutrition throughout the lifecycle

“…The study in Mexico focused on adolescent girls and boys aged 12–19 years and showed that both a Western- and plant-based dietary pattern were simultaneously associated with overweight–obesity and at least one indicator of under-nutrition such as anemia [ 192 ]. In Ghana, time trends in anthropometry in adolescent girls aged 15–19 years showed that thinness and stunting had declined since 2003, but that the prevalence of overweight and obesity had increased by 40%, while anemia remained severe [ 11 ]. There is a double burden of malnutrition as evident in this vulnerable group, and becoming even more prominent, suggesting that obesity and anemia can co-occur in the same girls, which needs to be taken into account in dietary advice and nutrition programs.…”
