This study sought to determine the influence of sense of coherence (SOC), a personal stress-coping resource, and smoking on the self-reported gingival health of a cohort of rural black South African adolescents.
This 18-month study involved a three-wave survey of a representative sample of eighth graders from 11 randomly selected high schools in the Limpopo province, South Africa (n=970). Using a generalized estimating equation model, we examined the correlates of recent gingivitis, defined as self-reporting frequent gingival bleeding (GB). Explanatory variables included baseline socio-economic status, age, gender, plaque levels, toothbrushing frequency, tobacco use status and SOC levels.
Among our sample, 74.6% reported experiencing gingivitis at some point during follow-up, while 41.9% reported frequent GB at the last survey. Factors that were positively associated with recent gingivitis include living in poor households [odds ratio (OR)=1.49; p<0.01], having higher plaque levels (OR=1.18; p=0.04) and smoking regularly (OR=1.57; p=0.04). Self-reporting gingivitis was negatively associated with being female (OR=0.76; p=0.02) and having a higher SOC (OR=0.96; p<0.001).
Adolescent smoking and SOC levels are independent predictors of self-reported gingivitis. Therefore, in addition to plaque control, smoking prevention and the teaching of stress-coping skills may be important interventions for promoting adolescents' gingival health.
本研究旨在确定连贯感（一种个人应对压力的资源）和吸烟对一组南非农村黑人青少年自我报告的牙龈健康的影响。
这项为期18个月的研究包括对南非林波波省11所随机选择的高中八年级学生的代表性样本进行的三轮调查（n = 970）。我们使用广义估计方程模型，研究了近期牙龈炎的相关因素，近期牙龈炎定义为自我报告经常牙龈出血（GB）。解释变量包括基线社会经济地位、年龄、性别、牙菌斑水平、刷牙频率、烟草使用状况和连贯感水平。
在我们的样本中，74.6%的人报告在随访期间的某个时间点患过牙龈炎，而在最后一次调查中，41.9%的人报告经常牙龈出血。与近期牙龈炎呈正相关的因素包括生活在贫困家庭[比值比（OR）= 1.49；p < 0.01]以及牙菌斑水平较高（OR = 1.18；p = 0.04）和经常吸烟（OR =
