Childhood and Infant exposure to famine in the Biafran war is associated with hypertension in later life: the Abia NCDS study.

There are very few studies in Africans investigating the association between early life exposure to malnutrition and subsequent hypertension in adulthood. We set out to investigate this potential association within an adult cohort who were born around the time of the Biafran War (1968-1970) and subsequent famine in Nigeria. This was a retrospective analysis of Abia State Non-Communicable Diseases and Cardiovascular Risk Factors (AS-NCD-CRF) Survey, a community-based, cross-sectional study that profiled 386 adults (47.4% men) of Igbo ethnicity born in the decade between January 1965 and December 1974. Based on their date of birth and the timing of the famine, participants were grouped according to their exposure to famine as children (Child-Fam) or in-utero fetus/infant (Fet-Inf-Fam) or no exposure (No-Fam). Binomial logit regression models were fitted to determine the association between famine exposure and hypertension in adulthood. Overall, 130 participants had hypertension (33.7%). Compared to the No-Fam group (24.4%), the prevalence of hypertension was significantly elevated in both the Child-Fam (43% - adjusted OR 2.47, 95% CI 1.14-5.36) and Fet-Inf-Fam (44.6% - adjusted OR 2.54, 95% CI 1.33-4.86) groups. The risk of hypertension in adulthood was highest among females within the Child-Fam group. However, within the Fet-Inf-Fam group males had a equivalently higher risk than females. These data suggest that early life exposure to famine and malnutrition in Africa is associated with a markedly increased risk of hypertension in adulthood; with sex-based differences evident. Thus, the importance of avoiding armed conflicts and food in-security in the region cannot be overstated. The legacy effects of the Biafran War clearly show the wider need for ongoing programs that support the nutritional needs of African mothers, infants and children as well as proactive surveillance programs for the early signs of hypertension in young Africans.

Ebola epidemic--the Nigerian experience.

The current West African ebola epidemic has been described as the most unprecedented in the history of the disease. Nigeria reported its first case of the disease in July, 2014, at the end of the epidemic 20 people were infected and eight of them died. The epidemic resulted in increased knowledge of the disease as well as some misconceptions, increase in household and community hygiene practice and change in social interaction between affected individuals and the community. Prompt response by the government, with the support of international partners and proactive engagement of public health measures resulted in the rapid control of the epidemic; an experience the country hopes to leverage upon in subsequent epidemics.

Abia State HIV epidemic and response: challenges and prospects.

Since the first seroprevalence survey in 1999, the HIV prevalence in Abia State has increased from 1.8% to 7.3% in 2010. The state is currently experiencing a generalized epidemic, with most transmission occurring through heterosexual low-risk sex. Drivers of the epidemic include low knowledge of HIV prevention, low risk perception, predominantly male factor-driven risky sexual behavior, and low condom use. This study reviewed the state HIV epidemic trend in relation to response, sought to identify the gaps between the epidemic and response, and recommended measures to strengthen the state response.

Perception of quality of maternal healthcare services among women utilising antenatal services in selected primary health facilities in Anambra State, Southeast Nigeria.

BACKGROUND: This is a cross-sectional descriptive study aimed at assessing antenatal care service attendees' perception of quality of maternal healthcare (MHC) services in Anambra State, southeast Nigeria. MATERIALS AND METHODS: A total of 310 pregnant women utilising antenatal care (ANC) services in three purposively selected primary health centres (PHCs) in rural communities in Anambra State were studied. Reponses were elicited from the participants selected consecutively over a 4-month period, using a pre-tested, semi-structured interviewer-administered questionnaire on socio-demographic characteristics, utilisation and perception of MHC services. Data collected were analysed using SPSS version 17. RESULTS: Findings showed that utilisation of facility for both antenatal (97.0%; 95% CI, 94.4-98.4%) and natal services (92.7%; 95% CI 89.2-95.2%) were quite high. Generally, most of the women were satisfied with MHC services (89.7%). Most of them were satisfied with the staff attitude (85.1%), waiting time (84.1%) and cost of services (79.5%). Being ≥30 years (X (2) = 4.61, P = 0.032), married (X (2) = 9.70, P = 0.008) and multiparous (X (2) = 9.14, P = 0.028), as well as utilisation of formal health facility for antenatal (X (2) = 26.94, P = 0.000) and natal (X (2) = 33.42, P = 0.000) services were associated with satisfaction with maternal health services. CONCLUSIONS: The study showed high level of satisfaction with quality of maternal health services among antenatal attendees and highlights the need to strengthen interventions that increase uptake of formal MHC services.

Socioeconomic status and obesity in Abia State, South East Nigeria.

BACKGROUND AND OBJECTIVES: Obesity is a major risk factor for cardiovascular disease in developed and emerging economies. There is a paucity of data from Nigeria on the association between socioeconomic status and obesity. The aim of this study is to highlight that association in Abia State, South East Nigeria. MATERIAL AND METHODS: This was a cross-sectional survey in South East Nigeria. Participating subjects were recruited from the three senatorial zones of Abia state. A total of 2,487 adults took part in the study. The subjects were classified based on their monthly income and level of educational attainment (determinants of obesity). Monthly income was classified into three groups: low, middle, and upper income, while educational level was classified into four groups: no formal education, primary, secondary, and tertiary education. Body mass index of subjects was determined and used for defining obesity. Data on blood pressure and other anthropometric measurements were also collected using a questionnaire, modified from the World Health Organization STEPwise Approach to Chronic Disease Risk Factor Surveillance. RESULTS: Overall, the prevalence of obesity in low, middle, and upper income groups was 12.2%, 16%, and 20%, respectively. The overall prevalence of obesity in individuals with no formal education, primary, secondary, and tertiary education was 6.3%, 14.9%, 10.5%, and 17.7%, respectively. Educational status was found to be significantly associated with obesity in women, but not in men, or in the combined group. However, level of income was observed to be significantly associated with obesity in men, women, and in the combined group. CONCLUSION: Sociodemographic and socioeconomic factors are important determinants of obesity in our study population, and therefore may be indirectly linked to the prevalence and the outcomes of cardiovascular disease in Nigeria.

Blood pressure gradients and cardiovascular risk factors in urban and rural populations in Abia State South Eastern Nigeria using the WHO STEPwise approach.

BACKGROUND: Developing countries of sub-Saharan Africa (SSA) face a double burden of non-communicable diseases (NCDs) and communicable diseases. As high blood pressure (BP) is a common global cardiovascular (CV) disorder associated with high morbidity and mortality, the relationship between gradients of BP and other CV risk factors was assessed in Abia State, Nigeria. METHODS: Using the WHO STEPwise approach to surveillance of chronic disease risk factors, we conducted a population-based cross-sectional survey in Abia state, Nigeria from August 2011 to March 2012. Data collected at various steps included: demographic and behavioral risk factors (Step 1); BP and anthropometric measurements (Step 2), and fasting blood cholesterol and glucose (Step 3). RESULTS: Of the 2983 subjects with complete data for analysis, 52.1% were females and 53.2% were rural dwellers. Overall, the distribution of selected CV disease risk factors was diabetes (3.6%), hypertension (31.4%), cigarette smoking (13.3%), use of smokeless tobacco (4.8%), physical inactivity (64.2%) and being overweight or obese (33.7%). Presence of hypertension, excessive intake of alcohol, smoking (cigarette and smokeless tobacco) and physical inactivity occurred more frequently in males than in females (p<0.05); while low income, lack of any formal education and use of smokeless tobacco were seen more frequently in rural dwellers than in those living in urban areas (p<0.05). The frequency of selected CV risk factors increased as BP was graded from optimal, normal to hypertension; and high BP correlated with age, gender, smokeless tobacco, overweight or obesity, annual income and level of education. CONCLUSION: Given the high prevalence of hypertension in this part of Nigeria, there is an urgent need to focus on the reduction of preventable CV risk factors we have observed to be associated with hypertension, in order to effectively reduce the burden of NCDs in Africa.

Prevalence of abdominal obesity in Abia State, Nigeria: results of a population-based house-to-house survey.

BACKGROUND AND OBJECTIVE: Abdominal obesity is associated with the risk of developing disorders, such as diabetes and hypertension. The objective of this study was to investigate the prevalence of abdominal obesity in Abia State, Nigeria. MATERIALS AND METHODS: We carried out a cross-sectional study aimed at ascertaining the prevalence of abdominal obesity in Abia State, Nigeria. Participants in the study were recruited from communities in the three senatorial zones in the state. Screening for abdominal obesity was carried out in these subjects using waist circumference (the National Cholesterol Education Program Third Adult Treatment Panel criteria were used). The World Health Organization Stepwise Approach to Surveillance of chronic disease risk factors was used. Body mass index, anthropometric measurements, and other relevant data were also collected. RESULTS: Data on waist circumference were obtained from 2,807 subjects. The prevalence of obesity using body mass index in the population was 11.12%. In men and women, it was 7.73%, and 14.37%, respectively. The prevalence of abdominal obesity in the population was 21.75%. In men and women, it was 3.2% and 39.2%, respectively. CONCLUSION: The prevalence of abdominal obesity is high in Nigeria, and needs to be monitored because it is associated with increased cardiovascular risk.
