The diversity of Singapore's population affords a unique opportunity to study ethnic variability in the dementias. We sought to explore the effects of ethnicity on the frequency of Alzheimer disease and vascular dementia in a large Singaporean sample. A total of 357 patients were studied: 190 with vascular dementia and 167 with Alzheimer disease. Vascular dementia was more common among Chinese and Malays, whereas Alzheimer disease was more common in Indians and Eurasians. Factors that may contribute to the observed ethnic variability in dementia etiologies include differential frequency of the ApoE-e4 allele, frequency of vascular risk factors, lifestyle choices, and cultural attitudes toward health care utilization.

Within-family discussion on harmful effects of smoking and intention to initiate smoking among European adolescents

Masood M, Masood Y, Md Sabri BA, Younis LT, Yusof N, Reidpath D, et al.

J Addict Med, 2015 Jul-Aug;9(4):261-5.

PMID: 26241085 DOI: 10.1097/ADM.0000000000000127

OBJECTIVE: The main objective of this study was to determine the impact of discussion within family about the harmful effects of smoking on intention to initiate smoking in the long term among nonsmoking adolescents.
METHODS: Data from Global Youth Tobacco Survey for 25 European countries were used. The outcomes of interest were, therefore, the intention to initiate smoking 1 and 5 years after the survey. Discussion within family about harmful effect of smoking was the main predictor with age, sex, and smoking status of parents, friends, and classmates as covariates. The association between predictors and outcomes was assessed through multiple regression analysis.
RESULTS: A total of 118,703 nonsmoking adolescents were included. Within-family discussion significantly reduced the odds of intention to initiate smoking 1 and 5 years later. Intention to initiate smoking also was significantly associated with the smoking status of friends, classmates, and parents, except for father's smoking status, which was not associated with intention to initiate 1 year later.
CONCLUSIONS: This study demonstrated that within-family discussion about the harmful effects of smoking may contribute to reduce the intention to start smoking among adolescents in the long term. Such a discussion was associated with reduced intention to smoke even when adjusting for parent/friend and classmate smoking.

Malignant melanomas in the Eur-African-Malay population of South Africa

Isaacson C, Spector I

Am J Dermatopathol, 1987 Apr;9(2):109-10.

PMID: 3504109

Malignant melanoma is common among the whites of South Africa. In the black population, the tumor is much less frequent and occurs predominantly on the lower limb--particularly the sole of the foot. This study brings to light the anomalous situation that among the Eur-African-Malay population (those of mixed ancestry), malignant melanoma has probably the lowest incidence in the world.

Fulltext Vitamin A reserve of liver in health and coronary heart disease among ethnic groups in Singapore

Saha N, Ng TB, Tan PY, Wee KP

Br J Nutr, 1988 Nov;60(3):407-12.

PMID: 3219311 DOI: 10.1079/bjn19880112

1. The vitamin A content of human liver tissue was determined in 363 autopsy samples. The sample comprised a total of 181 subjects dying after accidents and 182 dying from coronary heart disease among Singapore ethnic groups of both sexes. 2. The medium vitamin A reserve was 146 mg/kg in accident victims and 141 mg/kg in those who had died of coronary heart disease. Of all the samples 16% contained less than 40 mg/kg, 45% had 100-300 mg/kg, while 9% contained more than 500 mg/kg liver. 3. Among the accident victims, Indians had the lowest median liver vitamin A reserve (118 mg/kg) compared with that in other ethnic groups (137 mg/kg in Chinese, 191 mg/kg in Malays, 155 mg/kg in Caucasians). 4. The ethnic distribution of vitamin A reserve in coronary deaths was similar to that in accident victims. 5. There was no significant difference between the sexes in hepatic vitamin A reserve. 6. The distribution of vitamin A reserve in all the groups was skewed to the right.

Cutaneous larva migrans in Hospital Kuala Lumpur, Malaysia: rate of correct diagnosis made by the referring primary care doctors

Yap FB

Trans R Soc Trop Med Hyg, 2011 Jul;105(7):405-8.

PMID: 21600621 DOI: 10.1016/j.trstmh.2011.04.002

A retrospective study was undertaken to determine the clinical features of cutaneous larva migrans (CLM) seen in the Department of Dermatology, Hospital Kuala Lumpur (Kuala Lumpur, Malaysia) and to assess the rate of correct diagnosis made by the referring primary care doctors. Clinical records of all 31 patients with CLM seen between January 2006 and June 2010 were retrieved. The majority of patients were male. The mean age was 32.2 years. Pruritus was reported in 83.9% of cases and serpiginous tracts in 100%. The mean lesion count was 4.4 and the mean duration of disease before presentation was 3.1 weeks. The majority of skin lesions were on the buttock and lower extremities. Only 45.2% of patients had the correct diagnosis made by the referring primary care doctors. Older age of patients and lower number of lesions were associated with a higher rate of correct diagnosis. The low rate of correct diagnosis made by the referring primary care doctors to the dermatologists in this study warrants the need for education of not only primary care doctors but also future primary care providers, consisting of medical students, house officers and junior medical officers.

Evidence of divergence with duration of residence in circulatory disease mortality in migrants to Australia

Gray L, Harding S, Reid A

Eur J Public Health, 2007 Dec;17(6):550-4.

PMID: 17353202

BACKGROUND: Very little is known about how acculturation affects health in different societal settings. Using duration of residence, this study investigates acculturation and circulatory disease mortality among migrants in Australia.

METHODS: Data from death records, 1998-2002, and from 2001 Census data were extracted for seven migrant groups [New Zealand; United Kingdom (UK)/Ireland; Germany; Greece; Italy; China/Singapore/Malaysia/Vietnam (East Asia); and India/Sri Lanka (South Asia)] aged 45-64 years. Poisson regression models were fitted to estimate the duration of residence effect (categorized in 5-year bands and also as having arrived 2-16, 17-31 and 32 years ago or more), adjusted for sex, 5-year age group and year of death, then additionally for occupational class and marital status (SES) on relative risks (RR) of CVD mortality.

RESULTS: Compared with the Australia-born population, CVD mortality was generally lower in each migrant group. Decreasing mortality with increasing duration of residence was observed for migrants from New Zealand (RR 0.95, 95% Confidence Interval 0.92-0.98, P<0.01, per 5-year increase), Greece (0.90, 0.86-0.94, P<0.01), Italy (0.94, 0.91-0.97, P<0.01) and South Asia (0.95, 0.91-0.99, P<0.01), mainly in older age groups. Trends remained after SES adjustment and also when broader categories of duration of residence were used. CVD mortality among migrants from the UK/Ireland appeared to converge towards those of the Australian-born.

CONCLUSIONS: These results show divergence in CVD mortality compared with the Australian rate for New Zealanders, Greeks, Italians and South Asians. Sustained cardio-protective behavioural practices in the Australian setting is a potential explanation.
