To study the relationship of polymorphic variants of the SLC6A4 gene with depression among people aged 25-44 years in Novosibirsk.
Under the WHO program «MONICA-psychosocial (MOPSY)», a random representative sample of people aged 25-44 years from the population of the Oktyabrsky district of Novosibirsk (men =725, mean age 43.4±0.4 years, response - 71.3%, women =710, mean age 44.8±0.4 years, response - 72%). Depression was assessed using the MONICA-MOPSY psychosocial questionnaire. Every fourth respondent was examined for polymorphic variants of 5HTTLPR-VNTR SNP rs25531 A>G of the SLC6A4 gene. The study was carried out within the framework of the budget topic Reg. No. 122031700094-5.
The high level of depression among people aged 25-44 was 12.8% (for men 9.1%, for women - 15.92%); the average level of depression occurred in 24.5% of the population (among men in 21.24%, among women in 26.76%) (χ=17.071, df=2, <0.001). The most common genotype of the SLC6A4 gene, among people aged 25--4 years old in Novosibirsk, was SLA - 43.29%, LALA - 26.53% - in second place, SS - 17.87% - third, LALG - 6 genotypes were less represented genotypes. 74%, SLG - 4.18%, LGLG - 1.39%. Carrying the SLA genotype (53.3% and 63.6%) increased the chance of developing both the average level of depression by 2.359 (95% CI 1.278-4.355) times, and depression in general by 1.933 (95% CI 1.142-3.271) times, compared with persons carrying the LALA genotype (32.0% and 46.9%), (χ=7.674, df=1, <0.01 and χ=6.095, df=1, <0.05). Persons carrying the LALG genotype (54.5%) also had a higher chance of developing a mean level of depression RR=2.929 (95% CI 1.039-8.261), compared with carriers of the LALA genotype (32.0%) (χ=4.326, df =1, <0.05) (<0.05).
Associative links between polymorphic variants of the SLC6A4 gene and depression have been established.
研究新西伯利亚25 - 44岁人群中SLC6A4基因多态性变异与抑郁症之间的关系。
在世卫组织“莫妮卡 - 心理社会（MOPSY）”项目下，从新西伯利亚十月区人口中随机抽取了25 - 44岁的代表性样本（男性 = 725人，平均年龄43.4±0.4岁，应答率 - 71.3%；女性 = 710人，平均年龄44.8±0.4岁，应答率 - 72%）。使用莫妮卡 - MOPSY心理社会问卷评估抑郁症。每四位受访者中就有一位接受SLC6A4基因5HTTLPR - VNTR SNP rs25531 A>G多态性变异检测。该研究是在预算课题编号为122031700094 - 5的框架内进行的。
25 - 44岁人群中抑郁症的高水平为12.8%（男性为9.1%，女性为15.92%）；抑郁症的平均水平出现在24.5%的人群中（男性为21.24%，女性为26.76%）（χ = 17.071，自由度 = 2，<0.001）。在新西伯利亚25 - 44岁人群中，SLC6A4基因最常见的基因型是SLA - 43.29%，LALA - 26.53%位居第二，SS - 17.87%位居第三，LALG - 6种基因型是较少见的基因型，占74%，SLG - 4.18%，LGLG - 1.39%。与携带LALA基因型（32.0%和46.9%）的人相比，携带SLA基因型（53.3%和63.6%）的人出现抑郁症平均水平的几率增加了2.359倍（95%置信区间1.278 - 4.355），患总体抑郁症的几率增加了1.933倍（95%置信区间1.142 - 3.271）（χ = 7.674，自由度 = 1，<0.01；χ = 6.095，自由度 = 1，<0.05）。与携带LALA基因型（32.0%）的人相比，携带LALG基因型（54.5%）的人出现抑郁症平均水平的风险也更高，相对风险RR = 2.929（95%置信区间1.039 - 8.261）（χ = 4.326，自由度 = 1，<0.05）（<0.05）。
已确定SLC6A4基因多态性变异与抑郁症之间存在关联。
