Background: Overweight and obesity rates among adolescents have increased substantially
over the years. This study aimed to determine the body mass index (BMI) of students and parents
and the relationship among media use, BMI, socio-demographic profiles, and snacking behaviour
during television watching of secondary school students in Kuching South City.
Methods: In accordance with the two-stage sampling method, a total of 316 adolescents aged
13–17 years from 7 secondary schools participated. Data were collected using questionnaire and
anthropometric measurement. Independent t test, one-way ANOVA, Mann–Whitney U test, and chisquare
test were performed.
Results: The mean BMI was 20.56 kg/m2 (SD 4.33) for boys and 20.15 kg/m2 (SD 3.91) for
girls. No significant difference in terms of z score for BMI-for-age or socio-demographic factors was
found. The mean duration of time devoted to media use was 4.69 hours (SD 2.93) on weekdays and
5.69 hours (SD 2.87) on weekends. Boys were found to spend more hours on media use than did the
girls (t = 4.293, P < 0.01). Respondents were reported to consume more cereal compared with soft
drinks and junk foods. Respondents whose fathers worked in the private sector devoted the fewest
hours to media use, whereas those with self-employed fathers devoted the most time to media use.
Respondents with mothers who were employed spent more time on media use than did respondents
whose mothers were housewives (F = 4.067, P < 0.01). No significant difference was found between
BMI and media time or snacking habits.
Conclusion: This finding indicated that media time has no effect on body weight, because
respondents were found to have normal weight and to consume less unhealthy food.

Introduction:
Non-adherence to antihypertensive medications is a leading cause of uncontrolled hypertension and its complications. However, data on the factors associated with non-adherence to antihypertensive medications in the communities of Sarawak, Malaysia, are limited. This study aimed to examine the prevalence and determinants of medication non-adherence among patients with uncontrolled hypertension.
Methods:
A cross-sectional study was conducted using the systematic sampling method in four government primary healthcare clinics in Sarawak. A self-administered questionnaire was used to obtain socio-demographic data and evaluate non-adherence. Blood pressure was measured, and relevant clinical variables were collected from medical records. Multivariate logistic regression was used to determine the determinants of medication non-adherence.
Results:
A total of 488 patients with uncontrolled hypertension were enrolled in this study. The prevalence of medication non-adherence was 39.3%. There were four predictors of medication non-adherence among the patients with uncontrolled hypertension: tertiary educational level (odds ratio [OR]=4.21, 95% confidence interval [CI]=1.67–10.61, P=0.010), complementary alternative medication (OR=2.03, 95% CI=1.12–3.69, P=0.020), non-usage of calcium channel blockers (OR=1.57, 95% CI=1.02–2.41, P=0.039) and 1 mmHg increase in the systolic blood pressure (OR=1.03, 95% CI=1.00–1.05, P=0.006).
Conclusion
Because of the high prevalence of medication non-adherence among patients with uncontrolled hypertension, primary care physicians should be more vigilant in identifying those at risk of being non-adherent. Early intervention should be conducted to address non-adherence for blood pressure control.
