Lower risk of venous thromboembolism in multiple Asian ethnic groups.

Lower risk of venous thromboembolism in Asians compared to Whites has been suggested. Despite the biological and cultural diversity of Asian Americans, data are sparse for specific ethnic groups. In our prior study of lower Asian American risk, the small number of subjects (337 in all races) precluded accurate study of specific Asian American groups. We present here a new study with 4674 venous thromboembolism subjects diagnosed between 1996 and 2015. Our study population was derived from 61,459 voluntary health examinees in a comprehensive northern California health plan with self-classified ethnicity: 53.0% Whites, 28.4% Blacks, 11.6% ASAMs, 6.8% Others. Of Asian Americans, 44.7% were Chinese, 32.8% Filipinos, 12.9% Japanese, 4.5% South Asians, and 5.0% Other Asians. Chinese, Japanese, Filipinos, and Other Asians each had lower venous thromboembolism risk than both Whites and South Asians, who had risk similar to each other. These data indirectly support a genetic explanation.

Alcohol intake, beverage choice, and cancer: a cohort study in a large kaiser permanente population.

The authors studied incident cancer risk from 1978 to 1985 and through follow-up in 2012 relative to light-to-moderate and heavy drinking and to the choice of alcoholic beverage in a cohort of 124,193 persons. With lifelong abstainers as referent, heavy drinking (≥ 3 drinks per day) was associated with increased risk of 5 cancer types: upper airway/digestive tract, lung, female breast, colorectal, and melanoma, with light-to-moderate drinking related to all but lung cancer.

Moderate alcohol intake and cancer: the role of underreporting.

PURPOSE: There is compelling evidence that heavy alcohol drinking is related to increased risk of several cancer types, but the relationship of light-moderate drinking is less clear. We explored the role of inferred underreporting among light-moderate drinkers on the association between alcohol intake and cancer risk. METHODS: In a cohort of 127,176 persons, we studied risk of any cancer, a composite of five alcohol-associated cancer types, and female breast cancer. Alcohol intake was reported at baseline health examinations, and 14,880 persons were subsequently diagnosed with cancer. Cox proportional hazard models were controlled for seven covariates. Based on other computer-stored information about alcohol habits, we stratified subjects into 18.4 % (23,363) suspected of underreporting, 46.5 % (59,173) not suspected of underreporting, and 35.1 % (44,640) of unsure underreporting status. RESULTS: Persons reporting light-moderate drinking had increased cancer risk in this cohort. For example, the hazard ratios (95 % confidence intervals) for risk of any cancer were 1.10 (1.04-1.17) at <1 drink per day and 1.15 (1.08-1.23) at 1-2 drinks per day. Increased risk of cancer was concentrated in the stratum suspected of underreporting. For example, among persons reporting 1-2 drinks per day risk of any cancer was 1.33 (1.21-1.45) among those suspected of underreporting, 0.98 (0.87-1.09) among those not suspected, and 1.20 (1.10-1.31) among those of unsure status. These disparities were similar for the alcohol-related composite and for breast cancer. CONCLUSIONS: We conclude that the apparent increased risk of cancer among light-moderate drinkers may be substantially due to underreporting of intake.
