Prevalence and factors influencing smoking amongst Malay primary school children in Tumpat, Kelantan.

The aims of this study were to determine the prevalence, knowledge and factors that influence smoking in Malay primary school children in Tumpat, Kelantan. A cross-sectional study was conducted in February 2004 among primary school children in Tumpat District. Two hundred-twelve children in standard one to six were randomly selected from three rural schools. An interview that included information on history of ever smoking, knowledge related to smoking and health, and potential factors that could influence smoking was done. Twenty-five children had previously smoked, with a prevalence of 11.8% (95%CI=8.0, 17.0) and 8 were current smokers (3.8%, 95%CI=1.2, 6.4). More than half (64.6%) of the children had a good knowledge of smoking. However, only 105 (49.5%) of them knew that passive smokers have a higher risk of developing diseases. Of those who had ever smoked, 12 (36.6%) were influenced by peers and 17 (51.5%) had a self-desire to smoke. The earliest age to start smoking was at 6 years. Factors found to be significantly associated with smoking on multivariate analysis were increasing age (OR=2.8, 95%CI=1.6, 5.1), being boys (OR=5.8, 95%CI=2.0, 16.8), being at second school level (standard 4, 5, 6)(OR=7.8, 95%CI=1.3, 45.3) and having other family members (excluding father) who smoked (OR=2.8, 95%CI=1.2, 6.5). However, having a father who smoked and a good knowledge were not reported as influencing factors.

Prognostic factors of differentiated thyroid cancer patients in Hospital Universiti Sains Malaysia.

INTRODUCTION: The aim of this study was to identify the prognostic factors that influence the survival of differentiated thyroid cancer patients treated at Hospital Universiti Sains Malaysia (HUSM). METHODS: A total of 178 patients diagnosed with and treated for differentiated thyroid cancer in HUSM between January 1974 and July 2003 were included in this retrospective cohort study. The additional follow-up period was one year after the end of the recruitment phase. The data was collected from the medical records of the patients. RESULTS: The overall five- and ten-year relative survivals of differentiated thyroid cancer patients in HUSM were 90.6 percent (95 percent confidence interval [CI] 84.4-94.4) and 85.3 percent (95 percent CI 76.0-91.2), respectively. The significant prognostic factors for differentiated thyroid cancer were age (hazard ratio [HR] 6.9; 95 percent CI 1.7-28.6), loss of appetite (HR 10.9; 95 percent CI 2.7-43.7), tumour size (HR 3.7; 95 percent CI 1.1-13.8), regional recurrences (HR 3.2; 95 percent CI 1.1-9.8), high-risk stage (HR 19.9; 95 percent CI 4.4-90.4), and treatment (HR 0.2; 95 percent CI: 0.1-0.5). CONCLUSION: The survival rates obtained in this study were slightly lower than other studies but the pattern of survival rates between groups were similar. Prognostic factors identified in this study were similar to those of other studies, suggesting that the experience of HUSM was almost similar with that of other institutions.

Risk factors of breast cancer in women in Kelantan, Malaysia.

INTRODUCTION: Breast cancer is the commonest cancer for females in Malaysia, with a prevalence of 86.2 per 100,000 women in 1996. Breast cancer mortality rate shows an increasing trend in Malaysia from 0.61 in 1983 to 1.8 per 100,000 women in 1992. The aim of this study was to identify the risk factors for breast cancer in women in Malaysia. METHODS: A matched case-control study was carried out at referral hospitals in Kelantan from July 2000 to June 2001. A standardised questionnaire that comprised socio-demographical factors, obstetrical and gynaecological histories, anthropometric measurements, and other potential risk factors for breast cancer, was used to interview 147 histologically-confirmed breast cancer patients and 147 controls. Controls were non-breast cancer patients who were matched for age and ethnicity, and excluded those with malignancies, or having gynaecological, hormonal or endocrine problems. Simple and multiple conditional logistic regressions were used for analyses. RESULTS: Factors contributing toward increased risk of breast cancer were nulliparity (odds ratio [OR] of 15.3; 95 percent confidence interval [CI] of 3.2, 72.4), overweight (OR of 2.1; 95 percent CI of 1.1, 3.9), family history of breast cancer (OR of 4.3; 95 percent CI of 1.3, 14.1) and previous use of oral contraceptives (OR of 2.5; 95 percent CI of 1.3, 4.8). CONCLUSION: This study reconfirmed that similar risk factors identified in Western populations were responsible for the occurrence of breast cancer in Kelantan. It also supported the theory that breast cancer occurrence was related to oestrogen exposure and familial factors. It suggested the importance of having children, maintaining ideal body weight and caution for oral contraceptive users and women with a family history of breast cancer.
