Correlation between oral health and body mass index (BMI) in 2071 primary school pupils

High weight and obesity represent risk factors for numerous diseases. Correlations between body mass index (BMI) and carious lesions have also been described. In the present study, a possible association between caries prevalence and high weight ranges were examined in 2071 primary school pupils (51.8 % girls, 48.2 % boys), aged 6 to 10 years. A dental examination including the assessment of carious lesions (df-t + DF-T) was followed by measurements of height and weight in order to determine the BMI. The evaluation showed that 6.8 % of the elementary school children were underweight, 76.4 % had a normal weight, and 10.5 % were overweight and 6.3 % obese. Underweight children showed healthy teeth in 50 % of the cases, 47.4 % with normal weight showed naturally healthy teeth, while overweight and obese children displayed naturally healthy teeth in 41.5 % and 38.3 % of the cases, respectively. In primary school pupils, a significant association between the caries frequency and the BMI was found. A low BMI showed a correlation with the absence of carious lesions (p < 0.0001), and a high BMI was linked to a high number of caries lesions (df-t + DF-T values; p = 0.0021). However, no gender-related differences, regarding the prevalence rates for high weight and obesity, could be established. The significant correlation between the BMI and caries frequency persisted even after adjustment to the age of the children.

Community screening for high blood pressure among adults in urban and rural Papua New Guinea

This is a cross-sectional study conducted intermittently in Port Moresby, the National Capital District of Papua New Guinea, from 1996 to 1997; Mt Obree in Central Province in October 2000; Upper Strickland River in April 2001; and the Balopa Islands in Manus Province in December 2002. The aim of the study was to determine the prevalence of high blood pressure and identify possible risk factors for hypertension in the 'healthy' population in Port Moresby and the three rural communities. There were 1491 subjects surveyed, 704 males and 787 females. Their ages ranged from 20 to 84 years. Just over 6% of subjects were aged 65 years and above. There were 205 (14%) smokers and 340 (23%) betelnut chewers. The Central (rural) subjects were generally younger with the lowest mean systolic and diastolic blood pressures and lowest body mass index (BMI) in both males and females (no overweight or obesity). In Central and Strickland the mean systolic (SBP) and diastolic (DBP) blood pressures were lower and remained the same in all age groups, then in females decreased with age after 55 years. The Manus (rural) subjects were older with higher mean systolic and diastolic blood pressures and higher mean BMI, surprisingly similar to the urban population of Port Moresby. The mean systolic blood pressures in Port Moresby and Manus increased with age in both sexes, while the mean diastolic pressure remained the same in all age groups in females and decreased after the age of 50 years. The prevalence of systolic hypertension among men and women was higher in Manus than in urban Port Moresby and, among the female subjects, Manus had the highest at 31%, while Central recorded the lowest for both males and females. The mean systolic blood pressures of betelnut chewers in Port Moresby, Manus and Central were lower (by 1-9 mmHg) but higher--in males only--in Strickland. The mean diastolic blood pressures of betelnut chewers were lower in all study sites. Both high BMI (overweight and obesity) and older age were significantly associated with high systolic blood pressure but betelnut chewing was significantly associated with lower mean SBP (p < 0.001), a protective effect against systolic hypertension.     

Association between high blood pressure and deep periodontal pockets: a nested case-referent study

A hypertension screening project was performed jointly at a dental clinic and a primary health care centre. In this report the hypothesis that there is an association between high diastolic blood pressure and deep periodontal pockets was tested. A total of 1,239 consecutive patients aged 35-65 years had their blood pressure measured before the dental examination or had a known hypertension. Information on medical history and tobacco use was obtained by interview and dental status was recorded. Fifty-four subjects had known hypertension and 141 had previously unknown diastolic blood pressure >90 mmHg (cases). For each case an age, sex and tobacco-use matched referent was chosen from those with diastolic blood pressure < or =90 mmHg. Significantly more cases than referents had periodontal pockets > or = 5 millimeters deep. In multivariate analyses the prevalence of deep periodontal pockets was associated with blood pressure status also after adjustment for the small differences between the groups in age, sex, tobacco use and number of teeth. In conclusion there was an association between diastolic blood pressure and prevalent deep periodontal pockets. Whether the relationship is a causal one remains to be explored. Screening for high blood pressure at regularly visits at the dental clinic may give the dental care a new important role in the public health field.

Yaws in the periurban settlements of Port Moresby,Papua New Guinea

Yaws is a re-emerging disease in Papua New Guinea. A resurgence of yaws is documented in the periurban settlements around Port Moresby. A total of 494 cases were identified from April 2000 to September 2001. The age distribution ranged from 2 years to adult (median 9 years). Presenting symptoms were adequately recorded in 286 cases (58%). Of these, 42% presented with raised painless sores, 47% with bone/joint symptoms only and 11% with both sores and bone/joint symptoms. Children in communities with a suspected high prevalence were surveyed and examined for presence of primary yaws sores. 33 out of 227 children examined (15%) had evidence of primary yaws sores. Initial control measures have been case-finding and treatment of contacts, but in areas of known high prevalence mass treatment is planned.     

北京市大兴区12岁儿童龋病调查

目的对北京市大兴区12岁儿童患龋状况进行调查分析，为进一步做好龋病的预防保健工作提供依据。方法通过随机抽样的方法选择520名12岁儿童进行口腔检查，采用问诊、视诊、探诊等方法检查龋病和龋齿的充填情况。结果北京市大兴区12岁儿童患龋率19．04％，龋齿充填率10．37％。结论北京市大兴区12岁儿童龋病较严重，而进行充填治疗的较少，所以有必要进一步加强儿童口腔卫生宣传教育工作及预防保健工作，降低儿童的患龋率，提高儿童龋齿充填率。     

家长对儿童口腔保健家庭医生签约服务意愿及影响因素研究

背景　儿童口腔患龋率高,事态严峻。而目前我国口腔医疗服务供给体系总量不足,分布不均,对于群体性的口腔保健服务供给不足。目的　本文旨在研究家长对儿童口腔保健家庭医生签约服务的意愿及其影响因素,为儿童全面、持续、协调的口腔预防保健服务后续推进及儿童龋齿的防治提供参考。方法　2019年10月-2020年1月,分层选取成都市武侯区内的6家社区卫生服务中心,将进行儿童保健的家长作为研究对象。采取偶然抽样方法,采集其基本信息、儿童及家长口腔情况和保健干预情况、口腔就医习惯,采用多因素Logistic回归分析影响家长儿童口腔保健签约服务意愿的因素。结果　共发放问卷311份,实际回收303份,有效回收率为97.4%。39.6%（120/303）的儿童发生过口腔疾病问题,11.6%（35/303）的儿童接受过窝沟封闭或涂氟预防措施,36.3%（110/303）的儿童接受过儿童口腔卫生指导,68.3%（207/303）的儿童家长有意愿接受儿童口腔保健签约服务。孩子是否曾经做过窝沟封闭或者涂氟等预防措施、是否接受过专业口腔卫生指导及家长口腔健康知识知晓情况,不同情况的家长对儿童口腔保健家庭医生签约服务意愿比较,差异有统计学意义（P<0.05）。多因素Logistic回归分析显示,孩子是否做过窝沟封闭或者涂氟等预防措施是家长对儿童口腔保健家庭医生签约服务意愿的影响因素（P<0.05）。结论　儿童做过窝沟封闭或者涂氟等预防措施的家庭、接受过专业口腔卫生指导的家庭及家长具备口腔健康知识的家庭,更愿意签约儿童口腔保健服务。大力持续深入开展学校儿童口腔疾病综合干预项目的同时,基层医疗卫生机构应结合儿童健康管理与学校卫生工作,以健康教育与预防性门诊干预为主,积极开展儿童口腔保健签约服务,覆盖全龄儿童,进一步降低患龋率。
