    Abstract:
    BACKGROUND: An increased allostatic load (cumulative physiologic wear and tear of the body) can lead to adverse health outcomes. Symptom experiences are known to influence allostatic load. Yet, the relationships between postpartum symptom typologies and maternal allostatic load remain unknown. METHODS: We used Community Child Health Network data and included participants with allostatic load data at 6, 12, or 24 months postpartum. Bivariate and multivariate analyses were conducted to examine associations between postpartum symptom typologies and (a) overall allostatic load, (b) allostatic load subscales for body systems (neuroendocrine, cardiovascular, metabolic, and inflammatory), and (c) individual biomarkers within the subscale. RESULTS: Overall allostatic load at 12 months postpartum was different by symptom typologies before (p = .042) and after adjusting for confounders (p = .029). Postpartum women in typology 5 (high overall) had the highest adjusted overall allostatic load (M = 4.18, SE = .27). At 12 months, adjusted allostatic load for the cardiovascular subscale was higher in typologies 3 (moderate-high sleep symptoms, M = 1.78, SE = .13) and 5 (high overall, M = 1.80, SE = .17). Within the cardiovascular subscale, those in typology 3 had higher adjusted odds for a clinically significant level of pulse rate (aOR = 2.01, CI = 1.22, 3.31). CONCLUSION: Postpartum women who experienced high symptom severity across all symptoms (typology 5) at 6 months had higher overall allostatic load at 12 months postpartum. Typologies 3 and 5 had the highest symptom severity in sleep-related symptoms and higher cardiovascular subscale scores. Postpartum symptom management should target symptom burden in an effort to reduce allostatic load thereby improving postpartum women's health outcomes.
