Confirmatory Factor Analysis of the Malay-Language Transtheoretical Model of Physical Activity among Malaysian Primary School Children

@#Introduction: The transtheoretical model (TTM) is an integrative model of intentional change consisting of stages of change, processes of change, decisional balance and self-efficacy. This study aimed at validating the TTM questionnaires on physical activity for Malaysian children using confirmatory factor analysis. Methods: The participants were 381 Malay students (188 male; 193 female), aged 10–12 years old, with a mean age of 10.94 (SD = 0.81). The original version of the TTM was translated into the Malay language using forward and backward translation. Certain phrases were adapted based on the local culture and vocabulary suitable for primary school students. Results: The final measurement models and their fit indices were: processes of change (CFI = 0.939, TLI = 0.925, SRMR = 0.040, RMSEA = 0.030); decisional balance (CFI = 0.897, TLI = 0.864, SRMR = 0.045, RMSEA = 0.038); and self-efficacy (CFI = 0.934, TLI = 0.915, SRMR = 0.042, RMSEA = 0.032). Conclusion: Care must be taken when using the TTM with children, as it has been prevalently validated with adults. The final version of the TTM questionnaire for Malay primary school children had 24 items for process of changes, 13 items for self-efficacy and 10 items for decisional balance.

Association between Polymorphisms of Insulin and Insulin Receptor Gene with Childhood Obesity in Malay Population / Jurnal Sains Kesihatan Malaysia

Childhood obesity is a global epidemic, which leads to the increasing number of studies on genetic locations associated with obesity-related traits. Polymorphisms of insulin (INS) gene have been shown to be associated with obesity-related phenotypes in Europeans; while insulin receptor (INSR) gene has been associated with energy regulation. Therefore, this study was conducted to investigate the association between the INS (rs689) and INSR (rs3745551) gene polymorphisms with childhood obesity risk in a Malay childhood population. Normal weight (538) and overweight or obese (557) children aged 6-12 years old were genotyped using semi-automated Sequenom iPLEX® Gold. Body mass index (BMI) was calculated from measured body weight and height. The rs689 (T/T: 0.006, A/T: 0.159 and A/A: 0.835) and rs3745551 (G/G: 0.054, A/G: 0.378 and A/A: 0.568) genotype distributions were consistent with Hardy Weinberg equilibrium. The T-minor allele frequency for rs689 was 8.6% and G-minor allele frequency for rs3745551 was 24.3%. Minor allele of INS gene polymorphisms significantly increased risk of obesity among Malay children (sex- and age-adjusted OR=1.580; 95%CI: 1.134-2.201). However, INSR gene polymorphisms were not significantly associated with childhood obesity. In conclusion, the polymorphisms of INS gene, rather than INSR gene, were associated with childhood obesity in the Malay population.

Depression and Coping Strategies Among Sexually Abused Children In A Malay Community In Malaysia

Objective: The fact that childhood sexual abuse is associated with depression is well-known. To date, there is no proper study done on screening for depression and coping strategies among sexually abused children in Malaysia. This study aimed to determine the prevalence of depression and examine the association of depression with the socio-demographics and coping strategies used by sexually abused children. Methods: Sixty-five sexually abused children who attended the One Stop Crisis Centre (OSCC) services at Hospital Universiti Sains Malaysia and fulfilled the study criteria were screened for depression using a validated Malay version of Children Depression Inventory (CDI).Depression was determined by a positive score of the Malay-CDI with depression being indicated in scores of more than 18. Results: In the study sample, 16 (24.6 %) participants had been depressed and 49 (75.4 %) participants had not been depressed. Having a confidante was a protective factor against depression. Short duration of time between the abuse incident and the clinical interview was significantly associated with depression. With respect to coping strategies, 59 (90.8 %) used emotion-focused strategies and 6 (9.2 %) used problem or task-focused strategies. Among emotion-focused coping strategies, participants did the following: deciding that nothing could be done to change things, were in denial, and suppressed their feelings. Conclusion: Twenty five percent of the sample suffered from depression. The screening of depression in the vulnerable group such as sexually abused children is important, particularly for early detection and treatment. By recognizing the coping strategies used in sexually abused children, the clinician could understand them better and plan for their psychological management.
