ABSTRACT
BACKGROUND: The sense of loneliness is one of the common problems of older people and their quality of life, and is affected by many factors such as personal resources, gender, health condition, and age. This study investigates the determinants of the sense of loneliness between older men and women in Birjand. METHODS: This study was a part of the community-based prospective cohort study of the Birjand Longitudinal Aging Study (BLAS). Individuals over 60 years of age and their families (selected by random cluster sampling) were assessed through structured interviews with questionnaires such as Patient Health Questionnaire, Short-Form-12, Longitudinal Aging Study Amsterdam Physical Activity Questionnaire, loneliness, and social support questions. RESULTS: The mean age of the participants in the study was 68.59 ± 6.72, and 53.2% were women. Based on the findings of pathway analysis, the most critical determinants of loneliness in older men and women were the number of children (total effect = -0.112, P = 0.006) and mood, respectively (total effect = 0.142, P < 0.001). According to results, older people with fewer children feel lonelier. CONCLUSION: Compared with men, emotional loneliness is more common in older women. Older women, who lost their husbands, suffer from loneliness, mental health disorders, and low quality of life.
