Worksite Environmental Interventions for Obesity Prevention and Control: Evidence from Group Randomized Trials

Effects of Obesity Management Program Provided by Occupational Health Nurse in Worksite

This study was conducted on 60 male adult technicians in the worksite to examine the impact of the obesity management program on their eating habits, exercise self-efficacy, quality of life, and body components. This was a nonrandomized pretest and posttest intervention study. The obesity management program was applied for 16 weeks on diet education, exercise, and counseling provided by the occupational health nurse in the worksite. The questionnaire for measure included the general characteristics, eating habits, exercise self-efficacy, and quality of life. Body components were measured by using the InBody 720 device. The participants who received the obesity management program showed better eating habits, a higher level of exercise self-efficacy, a higher level of quality of life, lower levels of body weight and body mass index (BMI), a smaller waist and hip circumference, and a higher level of muscle mass as compared with the preapplication.

Accumulating Data to Optimally Predict Obesity Treatment (ADOPT) Core Measures: Environmental Domain

BACKGROUND

There is growing interest in how environment is related to adults' weight and activity and eating behaviors. However, little is known about whether environmental factors are related to the individual variability seen in adults' intentional weight loss or maintenance outcomes.

OBJECTIVES

The environmental domain subgroup of the Accumulating Data to Optimally Predict obesity Treatment (ADOPT) Core Measures Project sought to identify a parsimonious set of objective and perceived neighborhood and social environment constructs and corresponding measures to include in the assessment of response to adult weight-loss treatment.

SIGNIFICANCE

Starting with the home address, the environmental domain subgroup recommended for inclusion in future weight-loss or maintenance studies constructs and measures related to walkability, perceived land use mix, food outlet accessibility (perceived and objective), perceived food availability, socioeconomics, and crime-related safety (perceived and objective) to characterize the home neighborhood environment. The subgroup also recommended constructs and measures related to social norms (perceived and objective) and perceived support to characterize an individual's social environment. The 12 neighborhood and social environment constructs and corresponding measures provide a succinct and comprehensive set to allow for more systematic examination of the impact of environment on adults' weight loss and maintenance.
