Consumption of sweetened beverages among schoolgoing children in a densely populated township in Lilongwe, Malawi

Background The growing global childhood obesity pandemic has not spared lowincome countries like Malawi, where 8% of children below the age of five years are overweight. Globally, regular consumption of sweetened beverages is implicated among the factors that fuel childhood obesity. Despite the growing problem, there are no local studies on any aspect of sweetened beverage consumption among children in Malawi that could help in guiding interventions and public health nutrition policies. Aim We aimed to assess sweetened beverage consumption among school-going children in Chilinde, a densely populated township in Lilongwe, the capital city of Malawi. Methods A total of 60 school-going children whose caregivers gave verbal consent were included, and a structured questionnaire was administered to the caregiver (or other knowledgeable and responsible member of the household) of each eligible child. Results Our results showed that 50 of the 60 children sampled were consuming a wide-range of sweetened beverages on a regular basis on any day of the week, mostly during meal times (n = 23), before going to school (n = 22), and after school (n = 19). One-third of the children were reportedly consuming up to 300 mL of several sweetened beverages per day. Conclusion Like in many countries around the world, consumption of sweetened beverages appears to be common among young school-going children in this urban setting in Malawi. As the country builds public health responses to the growing problem of non-communicable diseases, early preventive interventions among children should be given priority.

Response of some chickpea ( Cicer arietinum L.) genotypes to Orobanche foetida Poir. parasitism

In Tunisia, broomrape ( Orobanche foetida Poir.) causes major drawbacks especially in faba bean ( Vicia faba L.) Chickpea ( Cicer arietinum L.) suffers little damage compared to faba bean, but with the winter sowing chickpea cultivars, broomrape might become a serious problem for chickpea cultivation. The development of resistant cultivars remains the most efficient way to solve this problem. The behavior of six chickpea genotypes to O. foetida was studied under field natural infestation and artificial inoculation in pots and petri dishes in greenhouse conditions. During the cropping seasons 2010-2011 and 2012-2013 the level of infection was very low. The number of emerged parasites per host plant varied from 0.18 to 0.43 and the incidence from 6.5% to 23%. Among the six tested genotypes, G1, G2, and G4 showed partial resistance to O. foetida with low number and dry weight of emerged parasite and high grain yield compared to the other genotypes, although no significant differences were recorded. In pot experiments, the number and total dry weight of broomrape per plant were lower for G1 and G2 genotypes than the other genotypes. Parasitism does not affect significantly the shoot dry weight and number of pods of these genotypes. The total chlorophyll content was significantly reduced under infestation in all genotypes. In Petri dishes experiments, results showed that percent germination of O. foetida seeds varied from 49% to 65% and does not play a role in the resistance of chickpea genotypes. In contrast, broomrape attachment was lower and slower for the genotypes G1, G2, and G4 than the other genotypes. Resistance in chickpea genotypes was characterized by few parasite attachments on roots and a limited growth of established tubercles. No necrosis of attached tubercles was observed in the different experiments.

Polio eradication efforts in regions of geopolitical strife: the Boko Haram threat to efforts in sub-Saharan Africa.

The World Health Organization aims to eradicate wild poliovirus worldwide by the end of 2018. Cameroon and Nigeria, neighboring countries, have been affected by the terrorist and militant activities of the Islamist sect Boko Haram. Impacted regions are mainly the far North of Cameroon and Northern Nigeria. Targets of Boko Haram aggression in these zones include violence against polio workers, disruption of polio immunization campaigns, with consequent reduced access to health care and immunization. In addition to this significant problem, Northern Nigeria has historically seen rejection of polio virus vaccine initiatives. It remains to know how health systems can continue operations against polio in areas where Boko Haram operates. If appropriate measures are not urgently taken, it will be not possible to meet the 2018 goal of polio virus eradication. The response should include specialized immunization activities in conflict zones, will engagement of leaders. Countries should also explore immunization activities by soldiers and military personnel.
