Special Issue Information

Dear colleagues,

The Ellisras Longitudinal Study and other Non-Communicable Disease Studies International Conference organizing committee takes pleasure in inviting you to the 2nd International Conference on poverty and cardiovascular diseases from 3–5 December 2019 at the University of Limpopo and Ellisras/Lephalale. The major sub-themes for the conference include: 1) lifestyle risk factors for non-communicable diseases: tobacco and alcohol consumption; 2) nutrition, dietary intake and physical activity; 3) biological risk factors for non-communicable diseases: biochemical parameters, hypertension, genetics, lipid profiles, diabetes; 4) growth, maturation and ageing; and 5) child health and health education. The conference provides a unique inclusive platform for discussion by ordinary members of the Ellisras/Lephalale community, expert scholars, students and experienced professionals from all over the world offering a truly special international networking experience, as well as a comprehensive and interactive programme in which participants can cultivate their cross-cultural and communication skills while highlighting different topics related to poverty and cardiovascular diseases.

Keynote speakers for the conference include Prof. Han C.G. Kemper, Paediatric Exercise Physiologist and Epidemiologist, Principal Investigator of the Amsterdam Growth And Health Longitudinal Study, Amsterdam UMC, Amsterdam Public Health Research Institute, The Netherlands and Prof. Mahmoud U. Sani (MBBS, FWACP, FACP, FACC, FRCP Edin), MD and Cardiologist, Department of Medicine, Bayero University Kano/Aminu Kano Teaching Hospital, Nigeria. Preliminary speakers will also be scheduled at the conference.

The programme will have a long-lasting effect on the conference participants as well as the Ellisras/Lephalale communities, as the knowledge gained will be taken back to our respective communities and families. Only papers presented at the conference will undergo vigorous peer review and be considered for publication in this Special Issue of Children.

Genesis, Procedures, Attrition Rate and Major Reasons for Missing Measurement Session by the Study Participants in the Ellisras Longitudinal Study

The noncommunicable diseases’ (NCDs) profile is changing rapidly from one country to another. A well-formulated cohort study in Africa could answer major questions relating to the changing profile of NCDs risk in Africa. The aim of the present study was to outline the genesis, procedures, attrition rate and major reasons for study participants to miss measurement sessions in the Ellisras Longitudinal Study (ELS). Method: The ELS followed multiple longitudinal designs comprising repeated measurements in more than one cohort with overlapping ages. Age cohort and time of measurement effects could be identified. A cluster random sampling method was used to sample 2255 participants (1201 males and 1054 females), aged 2 to 10.9 years at baseline (November 1996). Information on lifestyle (tobacco and smoking, alcohol intake, physical activity and socioeconomic status) and biological risk factors for NCD and educational achievements were collected over time. The participants were followed 17 times over the past 25 years with measurements (blood pressure and anthropometry) collected twice during the first consecutive 8 years to account for growth dynamics and other health-related variables. The attrition rate for ELS sample for boys (14%–27.3%) was significantly (p < 0.05) higher than girls (7.9%–18.6%) from May 1999 to November 2003. There was a significant (p < 0.05) increase (25.3%–70.3%) in attrition rate from November 2009 to December 2015. The ELS participant migration to urban areas provided a unique opportunity to investigate the effect of urban life on these rural young adults given the previous data collected on the same subjects at a younger age (3–10 years at baseline in 1996). Conclusion: A well-formulated ELS study in Africa could answer major questions relating to the changing magnitude of NCDs risk factor profiles in Africa. Full article

An Assessment of the Relationship between Anthropometric Parameters and Blood Pressure among Polokwane Private School Children

High blood pressure (HBP) among children and adolescents has been associated with elevated risk of cardiovascular diseases later in life. The aim of this study was to determine the relationship between body composition and blood pressure among Polokwane private school children. Mean body fat % was significantly (P < 0.05) higher in girls (23.74) than the boys (16.77). There was a significant (P < 0.05) association between systolic blood pressure (BP) and waist circumference (WC) unadjusted (OR = 1.125) and adjusted (OR = 1.097) for age and gender. This study included a total of 1665 children and adolescents (846 boys and 819 girls) aged 5 to 15 years old. Anthropometric measurements including weight, height, hip circumference (HC) and waist circumference (WC) were taken according to standard procedures. Descriptive statistics were done to determine the prevalence of hypertension and mean of all the variables. Pearson correlation, linear regression and logistic regression were all done to determine the association between blood pressure (BP) and the anthropometric measurements. All statistical analysis were done using SPSS. There was a significant association between body composition and blood pressure among Polokwane Private School children. Lowering the risk factors of high BP in children and adolescents will lower their risk of cardiovascular diseases in adulthood. Full article

Cardiovascular disease (CVD) risk factors are known to begin early in life, but limited data on the relationship of obesity and hypertension with other known CVD risk factors, such as endothelial dysfunction, oxidative stress, and chronic low-grade inflammation is available on children. In this cross-sectional study involving 6–9 years old school children aged from the Eastern Cape Province of South Africa the relationship between obesity/hypertension and other risk factors for CVDs was investigated. General anthropometric parameters were measured, followed by blood pressure (BP) measurements and pulse wave velocity (PWV). Urine samples were collected for the determination of albumin, creatinine, asymmetric dimethylarginine (ADMA), 8-hydroxy-2deoxyguanosine (8-OHdG), and thiobarbituric acid-reactive substance (TBARS). Overweight/obesity (19.28%) and pre-hypertension/hypertension (42.16%) were prevalent in children. Mid-upper arm circumference (MUAC), a marker of obesity, was positively correlated with ADMA, while ADMA and PWV were significantly different (p < 0.05) between hypertensive and normotensive children. Also, TBARS and 8-OHdG were significantly (p < 0.05) increased in hypertensive subjects. Creatinine was significantly (p < 0.05) increased in obese, as well as in hypertensive children, and positively associated with waist circumference (WC) and neck circumference (NC). In conclusion, obesity and hypertension were associated with renal-cardiovascular disease risk, while oxidative stress showed a possible association with obesity in 6 to 9 year old South African children of African descent. This suggests that South African children of African descent may be becoming more prone to developing CVDs, and therefore may require early intervention for the prevention of CVDs in the near future.

Various studies have been conducted on children using the Ellisras Longitudinal Study Survey in South Africa, but none of these has addressed growth variations of children in this rural location. The aim of this paper is to assess the age at peak height velocity using the superimposition by translation and rotation (SITAR) method for both boys and girls in rural South Africa. The study is part of the on-going Ellisras Longitudinal Study, and has employed secondary data during the period from November 1996 to November 2003. The data was collected biannually in May and November each year. The Ellisras study initially followed a cluster sampling method. All participating children underwent a series of anthropometric measurements of height and weight according to the standard procedures recommended by the International Society for the Advancement of Kinanthropometry. The analysis was done using the SITAR model. Age at peak height velocity for Ellisras rural children was at 14.45 years for boys at 11.82 years for girls. Ellisras rural girls had their age at peak height velocity way earlier than Ellisras rural boys did by an estimated 2.63 years. Ellisras rural children and their growth variations were comparable to other studies. Full article
