目的通过恩格尔系数划分,探讨不同人群的生存状况和生命质量。方法于2005—2006年选取辽宁省沈阳、阜新和丹东市3 283名居民为调查对象,采用中文版简明健康调查量表(SF-36)进行生命质量调查;根据恩格尔系数划分不同人群,并进行生命质量比较和分析。结果恩格尔系数≥0.59、0.50~、0.40~、0.30~和<0.30水平组人群SF-36健康量表的生理总因子(PCS)得分分别为48.00、49.12、49.78、51.30和52.15分,心理总因子(MCS)得分分别为48.45、49.21、50.57、50.74和51.41分;生理、心理总因子得分均随恩格尔系数减少而增加;与恩格尔系数≥0.59组比较,恩格尔系数<0.50各组人群生理因子与心理因子得分较高,差异有统计学意义(P<0.05)。各年龄组人群SF-36量表生理和心理维度得分随恩格尔系数下降而升高。恩格尔系数<0.59的<66岁人群生理和心理各维度得分高于同年龄组恩格尔系数≥0.59人群。结论根据恩格尔系数划分的不同人群其生命质量不同,恩格尔系数越高则生命质量越差。 Objective To explore the living conditions and quality of life of different groups through the classification of Engel’s coefficient. Methods A total of 3 283 residents from Shenyang, Fuxin and Dandong in Liaoning Province were selected as the survey subjects from 2005 to 2006, and the Chinese version of the Simple Health Survey Scale (SF-36) was used for quality of life survey. Different groups were divided according to the Engel’s coefficient Life quality comparison and analysis. Results The total physiological scores (PCS) of the SF-36 health scale in the population with ENGEL≥0.59, 0.50 ~, 0.40 ~, 0.30 ~ and <0.30 were 48.00,49.12,49.78,51.30 and 52.15 respectively. The total psychological factors (MCS) scores were 48.45,49.21,50.57,50.74 and 51.41 points; physical and psychological total factor score decreased with the Engel coefficient increased; compared with the Engel coefficient ≥ 0.59 group, the Engel coefficient <0.50 The physiological and psychological factors in each group The factors score higher, the difference was statistically significant (P <0.05). Physiological and psychological dimensions of the SF-36 scale in all age groups increased with decreasing Engel’s coefficient. Engel’s coefficient <0.59 <66 years of age population physical and psychological dimensions score higher than the same age group Engel’s coefficient ≥ 0.59 population. Conclusions The quality of life varies among different groups of people based on the Engel’s Coefficient. The higher the Engel’s Coefficient, the worse the quality of life.
