The Mediterranean score of dietary habits in Chinese populations in four different geographical areas.

OBJECTIVE: To compare the dietary intake of Chinese people living in Pan Yu, Hong Kong, San Francisco and Sydney with respect to cardiovascular health, using the Mediterranean diet score, examining the effects of age, gender, urbanization and acculturation on the diet score. SUBJECTS: A total of 500 men and 510 women in Hong Kong were recruited as a territory-wide stratified random sample. Subjects were recruited in response to local advertisements for the other three sites: Pan Yu, 58 men, 95 women; San Francisco, 166 men, 192 women; Sydney, 95 men, 73 women. METHOD: Food-frequency questionnaire over a 7 week period. A high/healthy score was taken as > or =4 for men and >3 for women, representing a dietary pattern beneficial for cardiovascular health. RESULTS: In Hong Kong, more women in the middle age group (35-54) had a high score than other age groups, and overall more women had high scores than men. In comparing the four geographical regions, Pan Yu had the highest number of subjects with high score, and Hong Kong had the lowest. With the exception of the younger population and men in Hong Kong, the percentage of the population with a high score in all sites is greater than among elderly Greeks consuming a more traditional heart-healthy Mediterranean diet. CONCLUSION: Considerable variations in Chinese dietary patterns exist with respect to age, gender and geographic location. Overall, the Chinese diet is comparable to the Mediterranean diet and may be expected to have similar health benefits that have been documented for the traditional Mediterranean diet.

Assessment of total energy expenditure in a Chinese population by a physical activity questionnaire: examination of validity.

A physical activity questionnaire from which total daily energy expenditure (TEE) could be estimated was developed for adult Hong Kong Chinese subjects, and its reliability and validity examined. The questionnaire was based on questionnaires used in Caucasians, and adapted for local lifestyle after focus group meetings involving subjects of all age groups. The questionnaire was administered to 94 subjects, consisting of healthy adults, the elderly, and two patient groups (those with renal disease on continuous ambulatory peritoneal dialysis and those with cancer). Seventy-one subjects were reinterviewed within 14 days to test reliability. Validity was examined in 31 normal subjects by measuring the basal metabolic rate (BMR) by indirect calorimetry and multiplying by the physical activity level (PAL) obtained from published studies using the doubly labelled water method and also from FAO/WHO/UNU to obtain the TEE. The intraclass correlation coefficient of reliability rages from 0.7 to 0.8 for all subject groups. The mean estimated TEE from the questionnaire was not significantly different from the mean value derived from measured BMR x PAL. The mean bias ranged from an underestimation of 27 kcal to overestimation of 215 kcal. However, the limits of variability were wide. Age was inversely related to the energy expended for occupational activities, but was positively associated with energy expended in leisure activities. Women spent less energy on occupational and exercise activities, and more on caretaking activities. Those with disease were also less likely to participate in caretaking activities. We conclude that this questionnaire may be a useful tool for future studies where energy expenditure needs to be estimated in various settings in the Hong Kong Chinese population.

Statistical profile of traumatic brain injury: a Canadian rehabilitation population.

A retrospective clinical hospital chart study was undertaken to prepare a statistical profile of traumatic brain-injured patients in rehabilitation. It included 498 consecutive admissions to the Traumatic Brain Injury Rehabilitation Program of the Queen Elizabeth Hospital (Toronto, Canada) from 1978 to 1991. Descriptive statistics were obtained for age, gender, marital status, educational status, occupational status, history of drug and alcohol use, cause of injury, month of injury and length of coma. Comparisons are made between the studied population and several Canadian centres, as well as international brain injury demographics in the literature. Results are discussed in terms of the gender differences and lifestyle parameters associated with brain injury.

The key to successful program planning.

For program planning to be cost-effective, it must combine clear vision and realistic strategy. Reliable demographic information on target populations is essential, and in-house research can contribute substantially to the accuracy of information that health care administrators use in such planning. This article describes research into the traumatic brain-injured population at Toronto's Queen Elizabeth Hospital and discusses how this information can be used by health care administrators.
