[Coexistence of maternal overweight or obesity and stunted children in south-western Benin households]. / Coexistence du surpoids ou obésité et retard de croissance dans les ménages du Sud-ouest Bénin.

INTRODUCTION: To determine the prevalence and determinants of coexistence of maternal overweight or obesity and stunted children (DBM / SCOM) in south-western Benin households. METHODS: This cross-sectional study was carried out in June 2015 on 357 mother-child pairs randomly selected by a two-stage sampling technique in the city of Comè and its surroundings. Data on socio-economic factors, family, health care, dietary quality were collected by questionnaires, observation and documentary review. Anthropometric measurements were performed in mothers and children. A logistic regression analysis model was used to search for determinants of the coexistence of the two aspects of malnutrition. RESULTS: 19.3% of mothers were overweight and 5.7% were obese. 46% of children were stunted. The prevalence of DBM / SCOM was 11.5%. The main factors associated with DBM/SCOM were the child's age, the mother's occupation, ethnicity, social status and educational level, and the size, economic level, transportation means and food insecurity of the household. CONCLUSION: A high frequency of the coexistence of maternal overweight or obesity and stunting was observed in Comè households. Interventions based on the identified determinants are needed to act simultaneously on the double burden of malnutrition in Comè.

The household food insecurity access scale and an index-member dietary diversity score contribute valid and complementary information on household food insecurity in an urban West-African setting.

The number of urban poor is increasing quickly in West Africa, yet food security early warning systems still do not include urban areas. One reason is the lack of appropriate and internationally agreed-upon indicators to measure urban household food insecurity. Our objective was to assess the performance of the household food insecurity access scale (HFIAS) and an index-member's dietary diversity score (IDDS) to approximate the adequacy of urban households' diets. A survey was performed on a random cluster sample of 1056 households in Ouagadougou, Burkina Faso. Data on HFIAS and IDDS and 2 nonconsecutive household quantitative 24-h recalls were collected twice, in June-July and in November-December 2007. Diet adequacy was assessed through the household's mean adequacy ratio (MAR) using energy and 11 micronutrients. Structural equation modeling was used to quantify the association of each candidate indicator with the MAR and receiver-operating characteristic (ROC) analyses were performed to assess their targeting performance in predicting low or high MAR. HFIAS was negatively associated with the MAR [path coefficient (P) = -7.95 × 10(-3) ± 1.45 × 10(-3); P < 0.001], whereas IDDS was positively associated with it (P = 5.19 × 10(-2) ± 1.27 × 10(-2); P < 0.001). Areas under the ROC curves ranged from 0.585 to 0.661 for HFIAS and from 0.536 to 0.629 for IDDS. In conclusion, HFIAS and IDDS performed well in approximating adequacy of urban households' diets. They are informative indicators about urban food insecurity, promising for evaluation and monitoring but not for household targeting given their insufficient predictive power.
