This cross-sectional study aimed to analyse the social and gender-related factors influencing sedentariness in women, including occupation and family size (FS). We included women aged 45–70 years participating in the Breast Cancer Screening Programme of the Valencia Region (BCSP-VR) between November 2018 and October 2019 (n = 121,988). The response variable was sedentariness measured by sitting time in hours/day (h/day) (<3 h/day and ≥3 h/day). The explanatory variables were age, educational level, country of origin, living alone, childcare responsibilities, FS, disability, body mass index (BMI) and smoking status. Logistic regression models were adjusted for the whole sample and were stratified by occupation and FS. The variables that increased the odds of sedentariness were age ≥65 years (OR = 1.28; CI = 1.20–1.36), high educational level (OR = 1.39; CI = 1.31–1.47), non-manual occupation (OR = 2.38; CI = 2.27–2.48), living alone (OR = 1.11; CI = 1.05–1.17), disability (OR = 1.37; CI = 1.20–1.56) and BMI ≥ 30 (OR = 1.33; CI = 1.28–1.38). The variables decreasing the odds were large (OR = 0.90; CI = 0.87–0.96) and medium FS (OR = 0.93; CI = 0.90–0.97). Older age, high educational level and high BMI conferred a higher odd of sedentary lifestyle, independently of occupation and FS with statistical differences. Protective factors were childcare responsibilities in non-working women (OR = 0.86; CI = 0.74–0.99), large FS in women with manual occupations (OR = 0.88; CI = 0.80–0.97) and medium FS in housewives (OR = 0.91; CI = 0.86–0.97). This study identified social and gender-related inequalities in the factors influencing sedentariness, which were related to the type of occupation and FS. Highlights There are social and gender inequalities in the factors influencing sedentariness Non-manual occupation increases the risk of sedentary lifestyle Belonging to a medium or large family decreases the risk of sedentary behaviour Childcare responsibilities are related to lower sitting time throughout the day [ABSTRACT FROM AUTHOR] |
