Non-participation and adjustment for bias in case,control studies of periodontitis

EUROPEAN JOURNAL OF ORAL SCIENCES, Issue 5 2008
Rodrigo López
Periodontal researchers frequently use case,control studies, but information on participation rates and the reasons for participation are often missing in the publications, thus hindering the assessment of the validity of those studies. A nested case,control study based on a well-defined population was used to (i) describe the patterns of participation; (ii) show how some associations can be biased; and (iii) illustrate how inverse probability weights can be applied to reduce bias. Differential subject participation was quantified using the ratio between participation for each level and the overall participation. Possible biased associations were illustrated using the odds ratios found for eligible and participant subjects. Finally, we used the estimated probability that an individual participates in the case,control study conditional on that individual's covariate pattern, as observed in the screening study to attempt bias reduction. Considerable differential participation was observed for selected factors, including age, annual tuitions and fees, parental income, and parental education. The strategy used for adjustment of bias resulted in some degree of bias reduction. These findings challenge the inferential validity of many studies on periodontitis. The design and conduct of these studies should aim to improve subject participation and must consider and minimize this potential source of bias. [source]

Prevalence and impact of oral pain in 8-year-old children in Sri Lanka

INTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 2 2005

Summary.,, Objective., The present study aimed to determine the prevalence and impact of oral pain in 8-year-old Sri Lankan children and their parents. Design., A cross-sectional study using a multistage cluster sampling technique was carried out in a sample of 614 children attending schools in the Education Division of Badulla, Uva province, Sri Lanka. Data were collected by means of a pre-tested questionnaire that was sent to each of the children and their parents. The children were also given an oral examination. Of the 614 questionnaires which were sent to parents, 30 were not returned and eight had to be excluded from the analysis because the respondents had answered only two questions. Therefore, the present analysis is limited to data from 576 children and their parents. Results., The lifetime prevalences of oral pain, as reported by the children and parents, were 49% and 53%, respectively. According to the children's report, 25% had experienced oral pain in the past 2 months while 31% of the parents reported that their child had experienced oral pain within the same period. Of those children who reported that they had experienced oral pain in the past 2 months, nearly 45% stated that the pain was severe. In 48%, the pain was triggered when biting. ,Presence of cavity/decayed tooth' was cited as the most common cause of oral pain (67%). Overall, 74% of children had experienced a negative impact as a result of the pain whilst 66% of the parents said that the child's pain had had an impact on them. Ethnic group, parental income and level of education, and the caries experience of the child were significantly associated with the reporting of oral pain in the past 2 months. Conclusions., The prevalence of oral pain was high among these children, and had a considerable impact on both the children and their parents. [source]

Vulnerability related to oral health in early childhood: a concept analysis

mattheus d.j. (2010) Vulnerability related to oral health in early childhood: concept analysis. Journal of Advanced Nursing,66(9), 2116,2125. Abstract Aim., This article is a report of the analysis of the concept of vulnerability and its relationship to oral health in early childhood. Background., Poor oral health is a continued problem for children worldwide. Vulnerability increases the probability of poor oral health outcomes. The lack of clarity of the concept of vulnerability creates difficulty in understanding this multi-factoral condition. Data sources., Data source included 34 articles covering the period 2000,2009 from a variety of disciplines, including nursing, dentistry, medicine and public health. Methods., The concept analysis was conducted using Rodgers' evolutionary method. The literature was analysed and a social ecology model was used to frame the discussion, recognizing family and community influences on children's oral health. Results., The context of oral health in early childhood contributes to the changes in the concept vulnerability. The attributes are closely related to family and community factors and identified as limited parental income, parental education, community-based services and fluoride; and exposure to poor parental habits, parental neglect and harmful toxins. The primary antecedent is identified as a form of limited protection from exposure to various circumstances. Conclusion., Children with limited protection have increased vulnerability and greater probability of poor health outcomes. Nurses who understand the concept of vulnerability related to oral health and can identify factors that create protection and are capable of decreasing vulnerability through parent education, community awareness and policy changes that support children and families.

The Determinants of Child Labour: The Role of Primary Product Specialization

LABOUR, Issue 2 2005
Leonardo Becchetti
The paper tests predictions of a traditional intra-household bargaining model which, under reasonable assumptions, shows that lack of bargaining power in the value chain significantly reduces the capacity for obtaining benefits from increased product demand arising from trade liberalization and therefore is positively associated with child labour. Cross-sectional and panel negative binomial estimates in a sample of emerging countries support this hypothesis. They show that proxies of domestic workers' bargaining power in the international division of labour (such as the share of primary product exports) are significantly related to child labour, net of the effect of traditional controls such as parental income, quality of education, international aid, and trade liberalization. The positive impact of the share of primary product exports on child labour outlines a potential paradox. The paradox suggests that trade liberalization does not always have straightforward positive effects on social indicators and that its short-run effects on income distribution and distribution of skills and market power across countries need to be carefully evaluated.
