Abstract
INTRODUTCION Weight reduction in subfertile, obese women is important to increase the chance of spontaneous pregnancy and improve mother and child’s health. Lifestyle counselling by nurses may be an effective strategy to support subfertile, obese women to achieve weight loss. Previous research indicated that nurses can play a key role in lifestyle modification, however their attitude and self-efficacy can have negative effects on weight loss in patients. The aim of this study is to explore determinants of nurses’ behaviour in successful lifestyle counselling aimed at weight loss in obese patients in fertility care. METHOD We used data from a multicentre randomized controlled trail. The Lifestyle study assessed the costs and effects of a six-month structured lifestyle program aiming at 5-10% weight reduction in subfertile, obese women. Baseline characteristics of confounders and weight data of patients were derived from this study. To explore the role of nurses’ behaviour all intervention nurses that counselled patients in the lifestyle study participated in this observational study. The behaviour determinants, attitude, social influence and self-efficacy, and baseline characteristics were measured with a selfadministered questionnaire. RESULTS In total 290 patients were randomised in the lifestyle intervention arm of the Lifestyle study. This study analysed 168 completers and 45 patient-dropouts of the intervention program. Patients were excluded because of pregnancy (n=36), exclusion of their nurses (n=35)), lost to follow-up (n=5) or withdrew informed consent (n=1). In total 37 nurses counselled patients in the Lifestyle intervention arm, 24 nurses were taken into analyses. A total of 7 nurses were excluded, because they counselled less than 10 patients and 6 nurses dropped out. Comparison between completers and patient-dropouts of the lifestyle intervention program showed that completers had a higher initial weight, achieved more weight loss, scored higher on mental quality of life and work more often fulltime or >20 hours a week. The regression analyses showed that attitude, social influence and self-efficacy had no influence on weight loss in subfertile, obese women in the total study population as well in the completers group. CONCLUSION Lifestyle intervention programs led by nurses may be an effective strategy to support weight loss. This study shows that determinants of nurses’ behaviour attitude, social influence and self-efficacy does not influence weight loss in subfertile, obese women.
