Overweight or obesity caused by nutrition excess and lack of exercise will induce chronic diseases such as heart disease, diabetes, and hypertension. Chronic diseases not only threat the health but also impact on individual’s daily life , and they will interfere the quality of life and increase medical costs. The purpose of this study was to explore the effectiveness of eight weeks hospital-based weight control activities among coronary high risk patients.
By applying the intervention of diet control, regular exercise, and behavior modification to reduce body weight, waist-hip size, body mass index, blood lipids, fasting blood sugar, HbA1c, and blood pressure.
Study samples were selected from the members of weight control classes which were held by hospital in 2006-2008. Members who had BMI> 24 and with high blood pressure, high blood sugar, or high blood lipid were eligible for this study. Total samples were 34.
An experimental study design was used to compare the differences of pre-test and post-test data. The changes of samples’ body weight, waist-hip size, body mass index, cholesterol, triglycerides, high density lipoprotein, low-density lipoprotein, fasting blood sugar, HbA1c, and blood pressure were recorded.
Data was analyzed by SPSS 12.0. Sub-allocation, described statistics, and paired t-test were used in this study.
The study results were as follows: after eight-week weight control activities, in addition to the average of samples’ post-test high-density lipoprotein data did not increase, other post-test data average were lower than pre-test data average. Results of paired t-test also found that after eight-week weight control activities, the variables of body weight, waist-hip ratio, body mass index, cholesterol, triglycerides, fasting blood sugar, and HbA1c were significant, while low-density lipoprotein, high-density lipoprotein and blood pressure were not significant.
The study results supported that weight control activities held by hospital had the effectiveness of reducing body weight, waist-hip size , body mass index, cholesterol, triglycerides, fasting blood sugar and HbA1c. By means of preventing and reducing the risk from coronary heart diseases, it was recommended that medical institutions should promote such health promotion activities.
