Abstract

Abstract: Background: Bidirectional relationships between health-related quality of life (HRQoL) and breastfeeding outcomes during the perinatal period across different body mass index (BMI) groups have not been investigated. Understanding the nature of such relations can provide strategies the for development of targeted interventions. Objectives: This study aims to longitudinally (1) investigate the patterns of HRQoL during the perinatal period across different BMI groups; (2) explore bidirectional associations between HRQoL, breastfeeding attitude, and positive breastfeeding status during the perinatal period, and (3) compare the aforementioned relationships across four BMI groups. Methods: A three-wave prospective longitudinal design was adopted in the second and third trimesters and six weeks postpartum. Cross-lagged panel analysis was used to examine reciprocal relations between two domains of HRQoL, breastfeeding attitudes, and positive breastfeeding status from antenatal to postnatal periods. Multi-group analyses were conducted to determine whether different patterns exist in these relationships according to the four BMI groups. The BMI was self-reported. Breastfeeding attitude and HRQoL were measured by the Iowa Infant Feeding Attitude Scale and the Medical Outcomes Study Short Form Health Survey, respectively. Results: A total of 781 perinatal multi-ethnic women were recruited in Singapore. Our results showed that the physical HRQoL scores were the lowest at Wave 2 compared with those at Waves 1 and 3, whereas the mental HRQoL scores were the lowest at Wave 3 compared with those at Waves 1 and 2 across different BMI groups. Multigroup cross-lagged path analyses showed that breastfeeding attitudes were an antecedent of physical HRQoL in women with underweight. A cross-lagged relationship was found between breastfeeding attitudes and physical HRQoL scores across Waves 1 and 2 in women with obesity. Chi-square difference tests suggested that two paths (breastfeeding attitudes to Wave 2 physical HRQoL, and Wave 2 mental HRQoL to Wave 3 positive breastfeeding status) were significantly different across the four BMI groups. Conclusions: Physical and mental HRQoL patterns were different during the perinatal period, pre-conception counselling and perinatal care should be tailored to women's physical and mental health care needs. Reciprocal relations between physical HRQoL and breastfeeding attitudes during pregnancy were found in women with obesity. A flexible and individualised approach should provide for the woman with obesity in a respectful manner.
