There are few large surveys of periodontal disease in young age cohorts, and national surveys in Africa do not exist. This study assessed the prevalence and severity of periodontal disease in a national survey of adolescents and young adults in Morocco.
A multistage probability sampling design was used to draw a sample of 14,667 students 12-25 years old attending 87 schools. The sample was representative of approximately three million Moroccan students in this age group.
A total of 27.9%, 11.9%, and 7.7% of the subjects had ≥1 tooth with ≥4, ≥5, and ≥6 mm probing depth, and the population estimates were ≈ 822,436, 349,961, and 226,297 affected subjects, respectively. For attachment loss, the prevalences were: 11.6%, 9.5%, and 6.9% (or ≈ 341,761, 281,043, and 203,977 affected subjects) for ≥4, ≥5, and ≥6 mm, respectively. The rates of probing depth and attachment loss increased significantly with the increase in age (p < 0.01, p < 0.001). Sex and urban status did not show significant effects on the prevalence of periodontal disease (p > 0.05). Similarly, the relationship between the occupation status and periodontal status was modest and not statistically significant (p > 0.05).
Children and young adults attending public schools in Morocco have a high prevalence and severity of periodontal disease compared with other populations of similar age. The rate of periodontal disease reported here may be used as baseline population estimates in the surveillance of disease status in this population.
针对年轻人群体的牙周疾病大型调查较少，非洲尚无全国性调查。本研究在摩洛哥一项针对青少年和青年成年人的全国性调查中评估了牙周疾病的患病率和严重程度。
采用多阶段概率抽样设计，从87所学校中抽取了14667名12至25岁的学生作为样本。该样本代表了这个年龄组中约三百万摩洛哥学生。
分别有27.9%、11.9%和7.7%的受试者有一颗及以上牙齿的探诊深度≥4、≥5和≥6毫米，总体估计受影响的受试者分别约为822436、349961和226297人。对于附着丧失，≥4、≥5和≥6毫米的患病率分别为11.6%、9.5%和6.9%（或受影响的受试者分别约为341761、281043和203977人）。探诊深度和附着丧失率随年龄增长显著增加（p<0.01，p<0.001）。性别和城市状况对牙周疾病患病率无显著影响（p>0.05）。同样，职业状况与牙周状况之间的关系不明显且无统计学意义（p>0.05）。
与其他同龄人群相比，摩洛哥公立学校的儿童和青年成年人牙周疾病的患病率和严重程度较高。此处报告的牙周疾病发生率可作为该人群疾病状况监测的基线总体估计。
