e) To investigate the effect of intervention on the change in SBP, DBP, level of physical activity, dietary intake (total calorie intake, vegetable intake, fruit intake, plain water consumption percentage fat intake and salt intake), smoking, alcohol consumption and information-motivation-behavioural skills score in intervention group as compared to control group three months after intervention.
f) To investigate the effect of intervention on the change in SBP, DBP, level of physical activity, dietary intake (total calorie intake, vegetable intake, fruit intake, plain water consumption percentage fat intake and salt intake), smoking, alcohol consumption and information-motivation-behavioural skills score between intervention and control group at baseline and three months after intervention.
g) To investigate the effect of intervention on the change in SBP, DBP, level of physical activity, dietary intake (total calorie intake, vegetable intake, fruit intake, plain water consumption percentage fat intake and salt intake), smoking, alcohol consumption and information-motivation-behavioural skills score between intervention and control group at baseline and three months after intervention after adjusted for other factors.
