Abstract：Objective：To discuss the distribution rules of traditional Chinese medicine (TCM) syndrome types of patients with abdominal obesity complicated with vitamin D (VD) deficiency and the characteristics of their living habits. Methods： A total of 529 patients with abdominal obesity were selected as the study objects. The distribution rules of TCM syndrome types of patients with abdominal obesity complicated with VD deficiency and the characteristics of their living habits were summarized by face-to-face investigation， and the risk factors in living habits were analyzed. Results：Among the 529 patients with abdominal obesity， 79 cases(14.9%) were in the VD deficiency group and 450 cases (85.1%) in the VD non-deficiency group. In the VD deficiency group， the elderly accounted for 49.4% (39/79)， the middle-aged 24.1% (19/79)， and the young 26.6% (21/79)； there were significant differences in the comparison of cases among different age groups (P＜0.05). In the VD non-deficiency group， the elderly accounted for 53.1% (239/450)， the middle-aged 33.8% (152/450)， and the young 13.1% (59/450)； there were significant differences in the comparison of cases among different age groups (P＜0.05). The top five TCM syndrome types of patients with abdominal obesity complicated with VD deficiency were in sequence the blood stasis syndrome (65.8%)， spleen deficiency syndrome (50.6%)， qi deficiency syndrome (46.8%)， damp-heat syndrome (32.9%) and kidney deficiency syndrome (24.1%). The proportion of kidney deficiency syndrome of patients with abdominal obesity complicated with VD deficiency was 24.1%，higher than that of 14.9% of patients without VD deficiency (P＜0.05). In terms of living habits，patients with abdominal obesity complicated with VD deficiency preferred cold， spicy， and excessive oil food and cold drinks， and often had a higher proportion of sedentary lifestyle than that of patients without VD deficiency， and the proportion of eating white meat was lower than that of patients without VD deficency (P＜0.05). After pairwise comparison of alcohol intake， the proportion of VD deficiency in patients with abdominal obesity with drinking habit and without quitting alcohol was lower than that in those without drinking habit (P＜0.05). Sedentary lifestyle and dietary preference for cold food were risk factors for VD deficiency (P＜0.05)； drinking history was a protection factor (P＜0.05). Among some living habits without specific critical indicators， the levels of serum 25 (OH) D of patients with abdominal obesity were positively correlated with the frequency of eating breakfast，drinking dairy products and alcohol intake，and the duration of active exposure to sunlight (P＜ 0.05)， and negatively correlated with the frequency of drinking sugary drinks and the longest duration of daily continuous sitting (P＜0.05). Conclusion： Patients with abdominal obesity complicated with VD deficiency often have TCM syndrome types such as blood stasis，spleen deficiency，qi deficiency，dampheat and kidney deficiency. Compared with patients with abdominal obesity and without VD deficiency， patients with kidney deficiency syndrome are significantly more. In terms of living habits， it is recommended that patients with abdominal obesity avoid sitting for a long time， and instead do more outdoor sports， bask more， maintain regular habit of eating breakfast， eat more dairy products， and reduce raw and cold diets. In this study， drinking is a protection factor for VD deficiency， but it is not recommended to maintain drinking habits to improve VD deficiency.
