Under-fives Mortality Rates
Causes of under-fives mortality in Nigeria in 2008
The findings of this study have shown significant reductions in:
The prevalence rates of under-fives mortality between 1990 and 2012, in Nigeria (from 21.3% to 12.4%), Gambia (from 17.0% to 7.3%) and Senegal (from 14.2% to 6.0%).
 Under-fives mortality in Nigeria (42% reduction from 213 to 124 per 1,000 live births), Gambia (57% reduction from 170 to 73 per 1,000 live births) and Senegal (58% reduction from 142 to 60 per 1,000 live births) within the same study period.
These findings also showed that the under-fives mortality rates were significantly greater in Nigeria compared to Senegal (p<.05), but no difference compared to Gambia (p>.05) and no difference between Gambia and Senegal (p>.05).
Malaria was the 2nd main cause of under-5s mortality in Nigeria (25%), Gambia (27%) & Senegal (19%), while neonatal factors was the 1st in all 3 countries
DEMOGRAPHY
LOCATION:
Nigeria covers a surface area of 923, 708 km² and situated on the west coastline of Africa. It shares borders with Niger, Chad, Cameroon, and the Atlantic Ocean
 POPULATION:
177 M (approximately 2.46% of the world’s population with population density of 193 p/km².
BACKGROUND
Malaria is a preventable and treatable but very deadly disease that :
Affects million people annually and 1 million of the cases leading to death.
Prevalent in more than 100 countries where 40% of the world population resides, thus killing over 800, 000 African children annually.
African regions accounts for about 86% of an estimated 247 million malaria cases globally and 91% of deaths due to malaria .
Malaria significantly contributes to anaemia in expectant mothers and young children.
One child dies every minute .
Nigeria suffers the world’s largest malaria burden with almost 51 million cases and 207,000 deaths annually, 30% of which are under the ages of five, with about 1 in 20 of these children dying due to malaria-associated illnesses and 1 in every 8 Nigerian children not surviving their 5th birthday.
Malaria is the 3rd prominent cause of death in the under-5s globally, after pneumonia and diarrhoea. In Africa, after neonatal infections, malaria infection was the 2nd highest cause of mortality. Approximately 1 out of every 5 under-5s (20%) mortality is attributable to malaria.
Nigeria was significantly higher than Gambia & Senegal throughout study period.
Senegal was likely to meet MDGs target of 2/3 reduction in under-5 mortality (reduction to 46/1,000 live births by 2015; Gambia & Nigeria was still far from the target reduction of 51/1,000 & 71/1,000 live births respectively.
Causes of under-fives mortality in Gambia in 2008
Prevalence rates of mortality in Under-fives
CONCLUSIONS
Overall, the study suggests that malaria prevalence and under-fives mortality in Nigeria is still very high. Declining mortality rates in the under-fives observed during the study period was encouraging but cannot be accurately ascertained or generalised to the population. Further research could be carried out into the long-term impact of potential malaria interventions on under-fives morbidity and mortality in Nigeria in the next five years.
Prevalence Rates (PR)= under-5s mortality ÷ Country’s population x 100
PR decreased in all 3 countries between 1990 & 2012 (significantly lower in Nigeria followed by Gambia & then Senegal). Senegal had the highest reduction.
Senegal was the only country likely to meet the MDGs target by 2015 (PR in Senegal dropped to 6% in 2012, while Nigeria was still high at 12% and Gambia at 7.3%.
SPSS Tests
Lavene’s test for homogeneity– Sample variance do not differ significantly (p>.05)
ANOVA-(F(2,15) =4.93, p<.05 show significant main effect
Post-Hoc Bonferroni Test– Shows that under-5s mortality was greater in Nigeria vs Senegal (p<.05); no significant difference between Nigeria vs Gambia (p>.05) & Senegal vs Gambia (p>.05).
