Models are adjusted for age, sex, place of residence, marital status, education, occupation, household wealth, tobacco smoking, alcohol drinking, and fruits and vegetable intake. Multimorbidity is defined as the presence of two or more chronic conditions [angina pectoris, arthritis, asthma, low visual acuity, diabetes (excluding diabetes associated with a pregnancy), stroke, chronic lung disease, hypertension and depression].
