South Asians risk heart attack at younger ages

( from http://www.rxpgnews.com ) Washington, Jan 18 - South Asian people experience heart attacks at a younger age because of greater levels of risk factors such as smoking and diabetes earlier in life, according to a study by an Indian doctor.

The South Asian countries of India, Pakistan, Bangladesh, Sri Lanka, and Nepal account for about a quarter of the world's population and contribute the highest proportion of cardiovascular diseases compared with any other region globally.

Deaths related to cardiovascular disease occur five to 10 years earlier in South Asian countries than in Western countries, according to an article in JAMA, the Journal of the American Medical Association, a highly cited weekly medical journal.

This has raised the possibility that South Asians exhibit a special susceptibility for acute myocardial infarction - that is not explained by traditional risk factors.

Despite documenting the higher rates of earlier coronary heart disease - in South Asians, few studies have been able to shed light on its reasons.

Prashant Joshi, M.D., of the Government Medical College, Nagpur, India, and colleagues attempted to determine the reasons for the higher rates of CHD in native South Asians compared with individuals from other parts of the world. The study included 1,732 heart attack patients and 2,204 controls from 15 medical centres in five South Asian countries and 10,728 heart attack cases and 12,431 controls from other countries.

The researchers found that the average age for first heart attack was lower in South Asian countries - than in other countries -.

The prevalence of protective risk factors - were markedly lower in South Asian study participants compared with those from other countries.

Some harmful factors were more common in native South Asians than in individuals from other countries: history of diabetes, current and former smoking, history of hypertension, psychosocial factors such as depression and stress at work or home, and elevated ApoB/ApoA-I ratio -. When stratified by age, South Asians had more risk factors at ages younger than 60 years.

'The younger age of first AMI among the South Asian cases in our study appears to be largely explained by the higher prevalence of risk factors in native South Asians,' the authors write. 'These data suggest that lifestyle changes implemented early in life have the potential to substantially reduce the risk of AMI in South Asians.'

Good English gives better mental health to Asian Americans

( from http://www.rxpgnews.com ) Washington, Dec 1 - Indian and other Asian men with good or excellent English skills are less likely to have mental health problems than those with poorer English proficiency, according to a new study of immigrants to the US.

Asian Americans in general have lower rates of psychiatric disorders than American-born Asians and other native-born Americans with English-language proficiency the main variable among men and birthplace the key factor for women.

Asian-American immigrant women were far less likely to suffer from depression, anxiety, substance abuse or psychiatric disorder in their lifetime than were US-born women, according to this first national epidemiological survey of the community.

'Compared to all Americans, Asian Americans had lower lifetime rates of any disorder,' said David Takeuchi, a sociologist and University of Washington social work professor and lead author of the study published in the American Journal of Public Health.

'Roughly 48 percent of Americans will have some kind of a lifetime disorder. In our study, less than one in four Asian-American immigrants will have a disorder. However, that won't necessarily be the case for their children and grandchildren. If trends continue, rates for them will go up and that suggests that more investment is needed for prevention programmes.'

The researchers used a questionnaire designed by the World Health Organisation to find out about incidents in the past year and lifetime of depression, anxiety, phobias, post traumatic stress disorder, substance and alcohol abuse and eating disorders.

The questionnaire was available in six languages, although nearly three-quarters of the interviews were conducted in English.

The study also found that there were no significant differences among the main immigrant groups, the Chinese, Filipinos and Vietnamese.

Asian immigrants who came as elementary school-age children have an easier time learning English than older children, but are more at risk to develop a substance abuse problem.

American-born women are twice as likely to have a depressive disorder than Asian-born women.

Among men, those born elsewhere are less likely to have a substance abuse problem than Asian-American men born in the United States.

The study also raised a number of questions that Takeuchi said the researchers want to look at in the future. He said they would like to compare the circumstances of immigrants who voluntarily migrate and those who are refugees.

'Someone who is a voluntary immigrant doesn't typically suffer the severe trauma that a refugee who is fleeing persecution or war does.' And because social relationships can enhance or deter social mobility, the researchers also want to examine how discrimination is associated with mental health among Asian Americans.

Other papers in the journal look at the mental health of Latino and Black Caribbean immigrants to the United States. In general, all of the papers suggest that immigrants have lower rates of mental disorders than native-born Americans.

Data from the Asian-American paper was drawn from the larger National Latino and Asian American Study.

For this paper, the researchers interviewed nearly 2,100 native-born or immigrant Asian Americans who were 18 or older. Participants included 600 Chinese, 520 Vietnamese, 508 Filipinos and 467 other Asians including Japanese, Koreans and Asian Indians.
