N2  - INTRODUCTION: Obesity and low levels of physical activity are increasing among Pacific and Maori adolescents in New Zealand. AIM: To assess the feasibility of an after-school exercise and lifestyle programme to improve cardiorespiratory fitness, health and usual activity in less-active Pacific and Maori adolescents over six weeks. METHODS: Eighteen less-active secondary school students participated. The six-week programme included 3 x 1.5 hour exercise and healthy lifestyle sessions per week. Outcomes included estimated cardiorespiratory fitness (VO2 max), insulin resistance (Homeostasis Model Assessment), physical activity, glycated haemoglobin (HbA1c), fasting plasma glucose, blood pressure, waist circumference and fasting lipids, measured at baseline and six weeks. Programme attendance and qualitative comments were also recorded. Student?s t-tests were used. RESULTS: Of the 18 students enrolled, 16 (89%) completed six-week follow-up, 14 (78%) were female, 13 (72%) were Pacific ethnicity and 5 (28%) were Maori. At baseline, mean age was 16.3 (standard deviation [SD] 1.0) years, body mass index (BMI) 35.2 (SD 6.7) kg/m2 , VO2 max 31.5 (SD 4.3) mL/kg/min, systolic blood pressure 125.0 (SD 12.9) mm Hg, HbA1c 39.9 (SD 3.8) mmol/mol, fasting serum insulin 28.3 (SD 27.8) µU/mL. At follow-up, improvements had occurred in VO2 max (3.2 mL/kg/min; p=0.02), systolic blood pressure (-10.6 mm Hg; p=0.003), HbA1c (-1.1 mmol/mol; p=0.03) and weekly vigorous (4 hours, p=0.002) and moderate (2 hours, p=0.006) physical activity, although waist circumference increased (p=0.005). Programme attendance was over 50%. Comments were mostly positive. DISCUSSION: The after-school exercise and lifestyle programme and study methods were feasible. Such programmes have the potential to improve health outcomes for Pacific and Maori adolescents.
