Physical inactivity is a significant public health concern among adolescents. Social cognitive factors are suggested to influence physical activity including in students, However, it is unclear how these factors influence physical activity levels among students in the Education and Training Center in Riau. This study aimed to develop a prediction model of physical activity levels based on social cognitive predictors in this population. The study was a cross-sectional study of 107 students from the Education and Training Center in Riau who completed online questionnaires on physical activity and social-cognitive correlates. Physical activity levels were measured using the Physical Activity Vital Sign, while the social cognitive correlates included self-efficacy, outcome expectations, stress levels, and motivation, which were measured using validated scales. Simple and multiple linear regression analyses were conducted to analyze the data. The results indicated that self-efficacy, outcome expectations, stress levels, and motivation significantly predicted physical activity levels among students. The results of the multiple linear regression indicated regression coefficients were 0.26, 0.31,-0.33 and 0.27 for self-efficacy, outcome expectation, stress level and motivation practice, respectively. The multiple linear regression model, which included all variables, predicted 32.9% of the variance in physical activity levels. The findings suggest that physical activity promotion programs for students should focus on improving self-efficacy, outcome expectations, stress management, and motivation. Future research can focus on developing and evaluating the efficacy of physical activity promotion interventions that target social cognitive predictors among students.

Objective:To determine the risk profile of chronic kidney disease (CKD) patients.Methods:This is an observational cross sectional study involving 130 patients for which data was collected prospectively.. Sixty five subjects with an estimated glomerular filtration rate (eGFR) below 120 ml/min/1.73 m2 were recruited via random sampling technique from nephrology clinic in a tertiary nephrology referral center. Medical history, demographic data, urinary and serum biochemistry tests were obtained.Results:Most of the CKD patients who were referred to the nephrology clinic were asymptomatic. The most common laboratory abnormalities noted among CKD patients were proteinuria, anaemia and hyperkalaemia. Advancing age, pre-existing morbidities such as diabetes mellitus, hypertension and overweight are characteristics that are strongly associated with the referred CKD patients.Conclusions:Most of the referred CKD patients are in advanced age with diabetes, hypertension and overweight. Majority of the CKD remained asymptomatic despite in the advance stage of CKD. This strongly calls for cost effective screening for population at risk.
