Constipation is a health condition that presents a significant problem to the people suffering from it, generally defined as fewer than three bowel movements per week, and with great prevalence and impact on quality of life in adults and elderly people (Bub, Brinckmann, Cicconetti, & Valentine, 2006;Rao et al., 2015). It affects the overall well-being of individuals, has a multifactorial character, and can be influenced by physical, psychological, physiological, emotional, and environmental factors. Studies have reported an incidence of constipation among ambulatory adult patients over 65 old of 26% in men and 34% in women. Incidence is considerably higher in people living in nursing homes and hospitals than in those people living in the community (Lim & Childs, 2013). Dementia and acute stroke and palliative cancer patients are particular clinical conditions cited by researchers for constipation (Bub et al.Abstract Purpose: To identify nonpharmacological clinically effective interventions for constipation in adults. Methods: A systematic review of experimental studies of nonpharmacological interventions addressing participants' management of constipation using samples of adults over 18 years of age was conducted. In evaluating the methodological quality of the eligible studies, we used the assumptions of the Cochrane Collaboration, and for the reporting of items in the systematic review we used the Model of Preferential Reporting Items for Systematic Reviews and Meta-Analyses. The protocol of this review was recorded in the International Prospective Register of Systematic Reviews of the University of York under number 43693. Results: This review included 12 randomized controlled trials. Nonpharmacological effective interventions for the resolution of constipation were identified: individualized intervention based on the participant's modifiable risk factors of constipation promoting literacy in health; educational measures in dietary modification and lifestyle; and abdominal massage. Conclusions: Specific nonpharmacological interventions are crucial for nurses' clinical practice and of major importance for clients and families.Evidence on these interventions in resolving constipation is still scarce and fails to provide evidence-based data to support nursing clinical practice. Clinical Relevance: Personal lifestyles, comorbidities, medication, and sedentary habits are likely to be risk factors in constipation. Thus, it is important to invest in nonpharmacological interventions that promote changes in behavior regarding prevention or resolution of constipation. Moreover, nursing researchers worldwide should conduct research for clinical practice regarding the fundamentals of care.
