RESUMEN
BACKGROUND: Evidence on sociodemographic determinants and spatial variations in the fruit and/or vegetable (FV) consumption was reported. This study aimed to explore geographical and sociodemographic disparities in the level of FV consumption among adults in Burkina Faso, using the national baseline data. METHODS: This was a cross-sectional secondary study of primary data obtained by the 2013 (September to October) World Health Organization Stepwise Approach to Surveillance survey conducted in Burkina Faso. The participants were 4402 women and men aged 25-64 years and living in all 13 Burkinabè Regions. Descriptive and analytical analyses were performed using Student's t test, ANOVA, the chi-square test, Fisher's exact test and logistic regressions. RESULTS: The prevalence of a typical daily consumption of at least three servings was 4.1% (95% CI: 3.6-4.8) for fruits and 6.6% (95% CI: 5.9-7.3) for vegetables. The national prevalence of adequate FV intake was 5.1% (95% CI: 4.4-5.8), and for two Regions ("Centre-Ouest" and "Nord") the pooled prevalence was 22.4%, while in the other eleven Regions its was significantly lower, 2.4% (p = 0.0001). Using quartiles derived from the national level of consumption, each of these two Regions had a higher proportion (about 50%) of their participants in the fourth quartile (the higher level). The associated sociodemographic factors with the adequate intake were being rural residents (aOR = 1.7, p = 0.011) and women (aOR = 1.3; p = 0.03). CONCLUSION: Except for the Regions of "Centre-Ouest" and "Nord" of Burkina Faso, the prevalence of adequate consumption of FV was very low in its other eleven Regions. Measures to increase consumption in urban people are urgent while women should be the key actor in the family-based approaches implementation and the nutrition education promoting FV consumption.

BACKGROUND: The emergence of resistance to artemisinin derivatives in western Cambodia is threatening to revert the recent advances made toward global malaria control and elimination. Known resistance-mediating polymorphisms in the K13, pfcrt, pfmdr1, pfdhfr, and pfdhps genes are of greatest importance for monitoring the spread of antimalarial drug resistance. METHODS: Samples for the present study were collected from 244 patients with uncomplicated malaria in health centers of Bobo-Dioulasso, Burkina Faso. Blood sample was collected on filter paper before the subject received any treatment. The parasite DNA was then extracted and amplified by Polymerase Chain Reaction (PCR) to evaluate the prevalence of polymorphism of pfcrtK76T, pfmdr1 (N86Y, Y184F), and pfdhps (A437G, K540E). The K13 gene polymorphism was analyzed by nested PCR followed by sequencing. RESULTS: The overall results showed 2.26% (5/221) of K13 synonymous mutant alleles (two C469C, one Y493Y, one G496G, and one V589V), 24.78%, 19.58%, 68.75%, 60.9%, 53.7%, 63.8%, and 64.28%, respectively, for mutant pfcrt 76T, pfmdr1-86Y, pfmdr1-184F, pfdhfr51I, pfdhfr59R, pfdhfr108N, and pfdhps 437G. We did not report any mutation at codon 540 of pfdhps. CONCLUSION: These results provide baseline prevalence of known drug resistance polymorphisms and suggest that artemisinin combination therapies may retain good efficacy in the treatment of uncomplicated malaria in Burkina Faso.
