Bottom Line: Among the resulting 3 groups, significant interaction of criteria was observed for CD4+ and CD4/8 cells.Participants who attended classes and/or performed the supplementary individualized programs tended to maintain their immunological function and to experience a decrease in body fat percentage.However, few effects were noted in participants with poor adherence, even in the intervention group.

ABSTRACT

Background: Physical activity is known to prevent obesity and metabolic syndrome in middle-aged and elderly people; however, the effectiveness of a comprehensive health education program for male white-collar employees is uncertain.

Methods: Forty-three men volunteered to participate in this study and were randomly assigned into 2 groups. The intervention group participated in a 2-hour program comprising comprehensive health education and hot spa bathing, offered once every 2 weeks, in addition to individualized programs once a week, for 24 weeks. The control group received only general health guidance. We compared their lifestyle characteristics and physical and mental health criteria at baseline, immediately after the intervention, and 1 year after the end of the intervention.

Results: Rates of adherence to individualized programs were 60.0 +/- 27.2% and 30.5 +/- 29.6% at the end of the intervention and at 1 year after the end of the intervention, respectively. Significant (P < 0.05) interaction of criteria was observed for cluster of differentiation 4+ (CD4+) cells and the ratio of cluster of differentiation 4+ to 8+ (CD4/8) cells, which were used to represent the participants' immunological function. We divided the intervention group into 2 subgroups on the basis of their attendance. Among the resulting 3 groups, significant interaction of criteria was observed for CD4+ and CD4/8 cells. In addition, the high attendance group had the highest CD4+ count and CD4/8 ratio.

Conclusions: Participants who attended classes and/or performed the supplementary individualized programs tended to maintain their immunological function and to experience a decrease in body fat percentage. However, few effects were noted in participants with poor adherence, even in the intervention group.

Mentions: Figure 1 shows the study flow diagram. This study was announced between August and September 2006 on a website used exclusively by municipal office personnel in Unnan, Japan. The eligibility criteria were male sex, age from 30 to 57 years, and no contraindications for exercise or spa bathing. Workers were informed of the study by means of the website in the municipal office, intrasectional circular, and direct letters and e-mails to all eligible people. Of 311 male white-collar employees between the ages of 30 and 57 years, 43 volunteered to participate in this study. After explanatory meetings were held on September 25–26, all 43 volunteers (14% participation rate) agreed to be included in this study, regardless of whether they were assigned to the control group or the intervention group (no blinding for participants). Twenty-two and 21 volunteers were randomly assigned by lottery to the intervention and control groups, respectively. We first randomized the list of volunteer names using a common bingo lottery device, after assigning unique numbers to the volunteers in the list in the order of their application. We then assigned 22 signed sticks (intervention group) and 21 unsigned sticks (control group), which were drawn from sealed boxes, to the numbers for the volunteers. The lottery operation was performed by a third party, ie, a person other than authors, and the person in charge of intervention and evaluation. Concealment was confirmed after completion of the assignments.
