The association between self-assessed health status and individual health practices

We report the association between single health practices and self-assessed health status. Data were collected by telephone survey applied to all adults in a sample of households in metropolitan St. John's; questionnaires were completed for 3,300 subjects. Five health practices--smoking, exercise, sleep, weight and drinking--as defined by previous studies were compared with self-assessed health status--good or poor--using logistic regression; linear and quadratic functions were fitted, plots were prepared and the direction and strength of the associations studied using odds and odds ratios. For sleep, smoking, weight and exercise, our results confirm the definitions used in previous studies. Current non-drinkers in our sample do not report good health as frequently as moderate drinkers. Breakfast--which was analyzed by conventional cross-tabulation--showed no association with health status.
