Logistic regression analysis yielded that female gender （OR=1.488）， living in Doumen district （OR=1.942）， junior college/undergraduate level （OR=3.602）， postgraduate and above （OR=5.904）， irregular meal pattern （OR=3.320）， comorbid chronic diseases （OR=3.244）， disqualification of self-assessment （OR=3.414） and disqualification of mental health skill （OR=2.131） were risk factors for depression symptoms， whereas age ≥25 years old （of all age groups OR<1）， monthly per capita income >20 000 yuan （OR=0.438） and exercising ≥3 times a week （OR=0.431） were protective factors for depression symptoms. Age of 25~34 years old （OR=2.051）， living in Jinwan district （OR=1.729） or Doumen district （OR=1.901）， junior college/undergraduate level （OR=2.955）， postgraduate and above （OR=6.662）， irregular meal pattern （OR=2.741）， comorbid chronic diseases （OR=3.535）， disqualification of self-assessment （OR=3.325） and disqualification of mental health skill （OR=1.838） were risk factors for anxiety symptoms， while monthly per capita income of 6 001~9 000 yuan （OR=0.665） and exercising ≥3 times a week （OR=0.572） were protective factors for anxiety symptoms.ConclusionThe mental health status of adult residents in Zhuhai is affected by various factors， including gender， age， region of residence， education level， meal pattern， exercise frequency and chronic diseases. ［Funded by 2023 Zhuhai Medical Research Project （number， 2220009000227）］
