Individual-Social-Predictive Factors in Performing Daily Life Activities in Obese and ‎Overweight Patients after Coronary Artery Bypass Graft Surgery

Obese or overweight people are more likely to have complications after coronary artery bypass graft surgery (CABG). Performing this surgery in these patients affects the patient's postoperative ability to perform Activity Daily Living (ADL) and Instrumental Activities of Daily living (IADL). The aim of this study was to determine the predictive factors for performing activities in overweight and obese patients undergoing CABG.

An analytical, cross-sectional study with available sampling was conducted over a period of four months in 84 patients, one month after CABG. Data collection was done using a questionnaire including demographic and social characteristics, Charlson comorbidity index, Kats Index, and Lawton Instrumental Activities of Daily Living Scale. The collected data were analyzed using descriptive and inferential statistics.

The majority of obese and overweight patients (94%), one month after surgery, were independent of their ADL, while most of the units needed help and dependence on their IADL (88.1%). Logistic regression model showed that the variables of the sex (P = 0.004, OR = 10.51 CI 95% = 2.15-15.41), carotid artery involvement (P = 0.01, OR = 0.12, CI 95% = 0.02- 0.64) were predictors of ADL, IADL in these patients.

Obese and overweight people are impaired in IADL and attention to predictors of sex and carotid artery involvement in their return to normal life style after surgery is very important.
