and psychological distress, while a significant negative correlation was found between physical activity and well-being (r = -.125) and between the number of risk factors and physical activity (r = -.491). Adolescents at risk were significantly less active than those who were not at risk for NCDs. Chi-square analysis showed that significantly more female adolescents who smoked (63%) or were physical inactive (67.3%) were at risk for NCD’s than their male counterparts. More adolescents from poor schools were smoking (54.5%), drinking (60.7%) or physically inactive (72.4%) than from rich schools. Significantly more females (63.6%) and poor adolescents (66.4%) showed high psychological risk factors. Female adolescents from poor backgrounds were significantly less active than those from more privileged backgrounds. While a logistical regression indicated that socio-economic status, gender and psychological risk factors contribute significantly to physical inactivity, physical inactivity was a significant predictor of risk for NCDs among adolescents
