PURPOSE: We analyzed relationships between unhealthy alcohol and eating habits with physical activity and fitness of garbage collectors. METHODS: Fifty-four male garbage collectors who were 19 to 39 years of age (29.8 ± 5.2 years) reported their consumption of alcohol, dietary fat, and sugar-sweetened beverages. Their dietary fat and sugar-sweetened beverage intake was used to calculate an unhealthy score. Body adiposity using skinfold calipers, abdominal strength assessed by sit-ups, and maximum oxygen consumption (VO2max) using the Astrand-Ryhming nomogram were evaluated. Individuals wore a motion sensor (Digi-Walker, SW-200, Yamasa Tokei Keiki Co., Tokyo, Japan) on their waist for three days during work activities. RESULTS: Regression models analyzed relationships among age, excessive alcohol consumption, and unhealthy eating habits with physical activity and fitness. Excessive alcohol consumption was associated with poor abdominal strength (R = 0.39, adjusted R2 = 0.12, p = 0.027), and yielded borderline relationships with VO2max (R = 0.33, adjusted R2 = 0.08, p = 0.071), and number of steps during work activities (R = 0.34, adjusted R2 = 0.07, p = 0.089). Relationships between unhealthy eating habits (β = 0.279, p = 0.038) and weakened abdominal strength were maintained after age adjustment (β = 0.279, p = 0.038; R = 0.57, adjusted R2 = 0.29, p = 0.0001). CONCLUSION: Excessive consumption of alcohol, dietary fat, and sugar-sweetened beverages were associated with poor physical fitness of garbage collectors. A larger sample size may be needed to support relationships among excessive alcohol consumption, number of steps during work activities, and physical fitness.
