Systems science methods in public health: what can they contribute to our understanding of and response to the cost-of-living crisis?

BACKGROUND: Many complex public health evidence gaps cannot be fully resolved using only conventional public health methods. We aim to familiarise public health researchers with selected systems science methods that may contribute to a better understanding of complex phenomena and lead to more impactful interventions. As a case study, we choose the current cost-of-living crisis, which affects disposable income as a key structural determinant of health. METHODS: We first outline the potential role of systems science methods for public health research more generally, then provide an overview of the complexity of the cost-of-living crisis as a specific case study. We propose how four systems science methods (soft systems, microsimulation, agent-based and system dynamics models) could be applied to provide more in-depth understanding. For each method, we illustrate its unique knowledge contributions, and set out one or more options for studies that could help inform policy and practice responses. RESULTS: Due to its fundamental impact on the determinants of health, while limiting resources for population-level interventions, the cost-of-living crisis presents a complex public health challenge. When confronted with complexity, non-linearity, feedback loops and adaptation processes, systems methods allow a deeper understanding and forecasting of the interactions and spill-over effects common with real-world interventions and policies. CONCLUSIONS: Systems science methods provide a rich methodological toolbox that complements our traditional public health methods. This toolbox may be particularly useful in early stages of the current cost-of-living crisis: for understanding the situation, developing solutions and sandboxing potential responses to improve population health.

Sexual counselling for treating or preventing sexual dysfunction in women living with female genital mutilation: A systematic review.

BACKGROUND: Female sexual dysfunction is the persistent or recurring decrease in sexual desire or arousal, the difficulty or inability to achieve an orgasm, and/or the feeling of pain during sexual intercourse. Impaired sexual function can occur with all types of female genital mutilation (FGM) owing to the structural changes, pain, or traumatic memories associated with the procedure. OBJECTIVES: To conduct a systematic review of randomized and nonrandomized studies into the effects of sexual counseling with or without genital lubricants on the sexual function of women living with FGM. SEARCH STRATEGY: Cochrane Central Register of Controlled Trials, MEDLINE, African Index Medicus, SCOPUS, LILACS, CINAHL, ClinicalTrials.gov, Pan African Clinical Trials Registry, and other databases were searched to August 2015. The reference lists of retrieved studies were checked for reports of additional studies, and lead authors contacted for additional data. SELECTION CRITERIA: Studies of girls and women living with any type of FGM who received counselling interventions for sexual dysfunction were included. DATA COLLECTION AND ANALYSIS: No relevant studies that addressed the objective of the review were identified. CONCLUSIONS: Despite a comprehensive search, the authors could not find evidence of the effects of sexual counseling on the sexual function of women living with FGM. Studies assessing this intervention are needed. PROSPERO REGISTRATION: CRD42015024593.
