Sedentary lifestyle and physical fitness decline due to war-related complications lead to body composition changes in chemical warfare veterans and increase the risk of cardiovascular diseases. This study aimed to investigate the effect of eight weeks of interval aerobic training on body composition indices of chemical warfare veterans. This was a quasi-experimental study with a pre-test-post-test design. The sample consisted of 17 chemical warfare veterans with 35-25% disability percentage who were randomly assigned to either an experimental (10 subjects) or a control group (7 subjects). The chemical warfare veterans participated in an interval aerobic training program at 60-45% heart rate reserve intensity for eight weeks. Body composition indices were measured using a Body Composition Analyzer model 356 made in South Korea. Repeated measures ANOVA was used to compare pre-test and post-test means. Interval aerobic training had a significant effect on body weight, body mass index, waist-to-hip ratio, body fat percentage, fat-free mass, visceral fat levels, and visceral fat area. The training intervention did not have a significant effect on total body water, soft lean mass, and body minerals (P<0.05). The reduction in body weight, body mass index, body fat percentage, and visceral fat levels following eight weeks of interval aerobic training leads to a favorable change in body composition and a decrease in overweight and obesity and potentially obesity-related cardiovascular disease risk factors.

Well-being is a positive and stable state of mind that is directly related to the quality of life of caregivers and brings a sense of satisfaction and happiness. So measuring the well-being of caregivers with a valid instrument is important for researchers and clinicians. Hence, the present study was conducted to investigate the structural validity of the caregiver well-being scale (CWBS) in a sample of informal caregivers of chemical warfare elderly veterans.

The method of this study is cross-sectional for psychometric evaluation. The sample included 142 of informal caregivers of chemical warfare elderly veterans aged 60 and over in Sardasht city. Study participants were selected by convenience sampling technique. Psychometric evaluation of CWBS assessed through face and construct validity regarding WHO translation protocol. Face validity was evaluated based on the opinions of 6 experts review and construct validity investigated with confirmatory factor analysis. Moreover, Cronbach's alpha was used to evaluate internal consistency reliability. The software of SPSS.V.23 and AMOS.V.23 were used for data analysis.

Regarding the face validity, the expert panel evaluated and revised the items of the CWBS. CFA revealed that the CWBS structure model was indicated as a validated model for basic needs dimension (CMIN=1.329, GFI=0.986, CFI=0.995, RMSEA=0.048) and daily activity dimension (CMIN=2.236, GFI=0.961, CFI=0.946, RMSEA=0.094) in the context of Iran and the sample of caregivers of veterans. The Cronbach's alpha of the scale was 0.83.

The result showed CWBS is a valid and reliable scale for measuring caregiver well-being. This study recommended using Iranian CWBS in future research and policy-making after more consideration.
