Workplace Physical Activity Intervention

An Effectiveness Study of Workplace Physical Activity Intervention for Staff in a Hospital Setting

In this study, it investigates the effectiveness of workplace physical activity intervention for staff in a 100-bed hospital in Taipei City, Taiwan. The physical activity program takes group coaching and includes aerobic exercise, muscle strength and stretching in combination with nutrition education. The duration of the program is three months (8 sessions per month). The subjects of the study were recruited from full-time employees working at the hospital who attend the program. The recruited employees can take part in the program freely and chose types of activity by themselves. This study measures body mass index, muscle strength, body fat percentage, muscle strength, body mass index, daily energy expenditure, and exercise self-efficacy as the baseline. After 3-month program, we will evaluate the effectiveness of the program. The result is anticipated the greater frequent attendance, the more obvious effectiveness in outcomes.

Detailed Description

A three-month group coaching physical activity program in combination with nutrition education was developed for full-time employees working on a 100-bed hospital in Taipei City, Taiwan. Due to the setting that employees can take part in the program freely and chose types of activity by themselves. So participants may have various intensity of participation. This study aims to evaluate the effectiveness of pre- and post- 3-month workplace physical activity programs in body fat percentage, Muscle strength, body mass index, daily energy expenditure, and exercise self-efficacy. One group pretest-posttest design was used for the study by convenience sampling technique. Subjects were recruited from participants of the program. The intervention consists of : (1)education on nutrition: 2 times per month for 3 months, 1 hour/time ; and (2)physical activity: a three-month group coaching program (24 sessions), including three types of exercise courses such as aerobic exercise, muscle strength and stretching. All analyses were performed using Statistics Analysis System version 9.3 and the effects of the intervention were assessed by the paired t-test. Multiple regression analysis was used to determine the contribution of attendances of activities and behavior change stage to effectiveness of workplace physical activity. The level of significance was set at p < 0.05.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change from Baseline Body fat percentage at 3 months	Body fat percentage was the total mass of fat divided by total body mass, multiplied by 100. Estimate for body fat percentage was measured by dual frequency bio-electric impedance(BIA) body composition analyzer.	baseline, 3 month after intervention
Change from Baseline Muscle strength at 3 months	Muscle strength was assessed by hand grip strength using a grip strength dynamometer. The grip strength dynamometer can measure range from 5 to 100 kg. During the measurement, the subject stood upright and was asked to hold the grip with the dynamometer with the greatest strength. Take the maximum value after two measurements.	baseline, 3 month after intervention
Change from Baseline exercise self-efficacy at 3 months	The five-item self-efficacy questionnaire designed to measure confidence in one's ability to persist with exercising in various situations which included the following: tired, bad mood, don't have the time, on vacation, raining or snowing. An 7-point scale was used to rate each item of self-efficacy, scores range from 5 "not at all confident" to 35 "very confident". A score of 0 means "extremely low self-efficacy" and a score of 35 means" "extremely high self efficacy"	baseline, 3 month after intervention
Change from Baseline exercise behavior change stage at 3 months	exercise behavior change stage	baseline, 3 month after intervention

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change from Baseline body mass index at 3 months	Body mass index (BMI) was calculated as body weight (kg) divided by the square of the body height (meter) (m2). BMI was assessed using a body composition analyzer.	baseline, 3 month after intervention
Change from Baseline Daily energy expenditure at 3 months	Daily energy expenditure as an estimate of total kilo-calories of energy expended per day. Calculation from the seven-day physical activity recall questionnaire. Subjects were asked to list total activities in each category and quantifying the time spent (hour) in each activity over a seven-day period. Activities were classified by their energy requirements, expressed in terms of Metabolic Equivalent of Task (MET). Sleep = 1 MET; light activity = 1.0-2.9 MET (MET level: 1.5); moderate activity = 3.0-5.0 MET (MET level: 4); hard activity =5.1-6.9 MET (MET level: 6); very hard activity = 7.0 or greater MET (MET level: 10). Each activity's total kilo-calories of energy expended per day was calculated by the following equation: activity MET * times of having activity time(hours)*body weight(kg)/7 (day).	baseline, 3 month after intervention
