Resilience to stress and risk of gastrointestinal infections

• Background: Exposure to psychological stress can elicit a physiological response that may influence characteristics of the gastrointestinal mucosa, including increased intestinal permeability, in turn possibly increasing susceptibility to gastrointestinal infections. We investigated whether low stress resilience in adolescence is associated with an 'increased' risk of gastrointestinal infections in subsequent adulthood.Methods: Data were provided by Swedish registers for a cohort of 237 577 men who underwent military conscription assessment in late adolescence (1969-76). As part of the assessment procedure, certified psychologists evaluated stress resilience through semi-structured interviews. The cohort was followed from conscription assessment until 31 December 2009 (up to age 57 years). Cox regression assessed the association of stress resilience with gastrointestinal infections (n = 5532), with adjustment for family background measures in childhood and characteristics in adolescence. Peptic ulcer disease (PUD) in adulthood was modelled as a time-dependent covariate.Results: Compared with high stress resilience, lower stress resilience was associated with a 'reduced' risk of gastrointestinal infections after adjustment for family background in childhood, characteristics in adolescence and PUD in adulthood, with hazard ratios (and 95% confidence intervals) of 0.88 (0.81-0.97) and 0.83 (0.77-0.88) for low and moderate stress resilience, respectively.Conclusion: Lower stress resilience in adolescence is associated with reduced risk of gastrointestinal infections in adulthood, rather than the hypothesized increased risk.
