Reference values for the six-minute walk test in Nigerian adolescents aged 10 to 18 years

Objective: To determine baseline six-minute walk distance in Nigerian adolescents and establish its relationship with age, gender and anthropometric parameters.Methods: One hundred and eighty healthy adolescents (10 – 18 years) were recruited from three schools. Six-minute walk test was conducted as described by the American Thoracic Society. Demographic and anthropometric characteristics were related to achieve six-minute walk distance. A mathematical formula for predicting six-minute walk distance was generated.Results: The mean ± SD six-minute walk distance was 590.1 ± 72.02 m and was significantly longer in males (p= 0.001) among adolescents aged 10- 16 years. Age was the only characteristic significantly associated with six-minute walk distance following multiple linear regression analyses. The formulae, [six-minute walk distance = 317.3 + 21.5 x age (years) in males and 117 + 33.0 x age (years) in females] closely approximated to measured six-minute walk distance.Conclusion: This study has derived reference values for 6-minute walk test in adolescents; the use of these reference values should consider age and gender variations.Keywords: Exercise test; Six-minute-walk; Adolescents; Nigeri

Nutritional Status of Primary School Children in Ilorin-West LGA, Kwara State, Nigeria

Background: Malnutrition in children remains a global health problem in developing countries including Nigeria. Nearly half of all under-five deaths in Africa and South-East Asia can be traceable to malnutrition. The nutritional status of primary school children in Ilorin-West Local Government Area of Kwara State is not known, therefore the study set out to determine this and its associated factors.Methods: This study was a descriptive cross-sectional study carried out between February and May 2016 across 16 primary schools in Ilorin-West LGA. Four hundred and eighty school children aged 6-12 years were recruited into the study through a multi-stage sampling technique. Anthropometry was taken following standard procedures; weight was measured with a digital bathroom weighing scale (Camry, Model: EB9323H, China), while height was measured with a stadiometer (Seca Model: 213, USA). Anthropometric indices were determined. Data collected was analysed using the IBM Statistical Package for Social Sciences (SPSS) Tm version 20.0 for windows.Results: The prevalence of underweight, stunting, wasting and obesity were 3.0%, 5.0%, 4.4% and 1.0%, respectively. Stunting was more prevalent among female pupils, pupils attending the public primary schools and children of mothers with no formal education, while obesity was more prevalent in the private primary schools.Conclusion: The prevalence of obesity recorded in this study confirms the emerging concept of ‘the double burden of malnutrition,’ and poses a public health challenge to policy makers. It is recommended that community nutrition enlightenment campaigns be strengthened and possibly school meals be re-introduced to both private and public schools.
