During life span human body is exposed to numerous stressors, which force changes in internal environment, in order to adapt to present conditions. Allostatic load concept was created to measure the cumulative effect of those stressors on the body. The aim of the study was to compare allostatic load (AL) and indicators of frailty between urban and rural elderly from Greater Poland province. In all 216 female and male individuals aged ≥55 years were enrolled into the study. To determine AL following variables were measured: WHR, diastolic and systolic blood pressure, ratio of total to LDL cholesterol, HDL cholesterol, glycated hemoglobin, serum dihydroepiandosterone-sulfate, overnight urinary cortisol, adrenaline and noradrenaline. Measures of frailty included time to walk 15 feet and maximal grip strength. Results were analyzed and compared between eight groups according to: place of residence, gender and age subgroups. In general, rural elderly were characterized by higher AL values compared to their urban peers, and males had greater AL values compared to females. Significant gender-related differences were noted among rural individuals (55–69 years: 3.43 males vs 2.18 females; ≥70 years: 2.88 males vs 2.52 females). It was observed that younger urban and rural females had lower AL values compared to their older peers, opposite relation was noted in case of male participants. It was noted that rural females in both age subgroups had significantly stronger hand grip then urban peers. However, rural females needed more time to walk 15 feet compared to urban females. No age- or place of residence-differences in grip strength and time to walk 15 feet were found in case of males. To conclude, conditions of life and exposure to external stressors seemed to vary in a great extent between females and males from rural area, but not urban area. Differences in physical performance due to the place of residence were pronounced only in studied females.
