Alveolar bone pattern and salivary leptin levels among premenopausal obese women / Padrão ósseo alveolar e níveis salivares de leptina entre mulheres obesas na pré-menopausa

ABSTRACT Background: Systemic bone loss may lead to more severe periodontal destruction, decreasing local bone mineral density. Aim: A cross-sectional designed was performed to study associations among alveolar bone pattern, salivary leptin concentrations, and clinical periodontal status in premenopausal obese and eutrophic women. Methods: Thirty morbid obese (G1) and 30 normal-weight (G2) women were included. Anthropometric and periodontal measurements (probing depth - PD, clinical attachment levels - CAL, presence of calculus, bleeding on probing -BOP, and plaque accumulation) were assessed. OHIP-14 was used for assessment of oral health impact on quality of life. Panoramic radiography was used to obtain the panoramic mandibular index (PMI), mandibular cortical index (MCI), and mental index (MI). Intraoral periapical (PA) radiography was taken to measure the total trabecular bone volume. Leptin was measured in saliva of fasted overnight women. Results: Groups 1 and 2 differed in all anthropometric aspects, but height. Pocket depth, calculus, BOP, and plaque index were worse in G1. No differences between groups were found considering OHIP. Normal-weight subjects showed higher proportion of dense bone trabeculae than obese subjects for pre-molars, but not for molars. Mental and panoramic mandibular indexes did not differ and were in normal level. Leptin concentration was dependent only on BMI. Conclusion: Obesity affected the periodontal conditions, the alveolar bone pattern, and the salivary leptin concentration.

RESUMO Racional: A perda óssea sistêmica pode levar à destruição periodontal mais severa, diminuindo a densidade mineral óssea local. Objetivo: Investigar as associações entre padrão ósseo alveolar, concentrações de leptina salivar e estado periodontal em mulheres obesas na pré-menopausa e eutróficas. Métodos: Foram avaliadas 30 mulheres com obesidade mórbida (G1) e 30 com peso normal (G2). Foram analisadas as medidas antropométricas e periodontais (profundidade de sondagem - PS, nível clínico de inserção - NCI, presença de cálculo, sangramento à sondagem - SS e acúmulo de placa). O impacto da saúde bucal na qualidade de vida foi mensurado por meio do questionário OHIP-14. Radiografia panorâmica foi utilizada para obter o índice mandibular panorâmico (PMI), índice cortical mandibular (MCI) e índice mental (MI); já a radiografia periapical intraoral (AF) para medir o volume ósseo trabecular total. A leptina salivar foi coletada no período da manhã com a paciente em jejum. Resultados: Os grupos 1 e 2 diferiram em todos os aspectos antropométricos, exceto em estatura. Profundidade de bolsa, cálculo, SS e índice de placa foram piores no G1. Não foram encontradas diferenças entre os grupos considerando o OHIP. Indivíduos com peso normal apresentaram maior proporção de trabéculas ósseas densas do que os obesos para pré-molares, mas não para molares. Índices radiomorfométricos não diferiram entre os grupos e estavam dentro de valores normais. A concentração de leptina esteve associada ao IMC. Conclusão: A obesidade afetou as condições periodontais, o padrão ósseo alveolar e a concentração de leptina salivar.

Prevalence of Overweight and Obesity among Students Aged 7-22 Years in Jiangsu Province, China / 生物医学与环境科学（英文）

<p><b>OBJECTIVE</b>To report the prevalence and trend of overweight and obesity among students aged 7-22 years in Jiangsu, 2010 to 2013.</p><p><b>METHODS</b>This cross-sectional study was carried out as part of students physical fitness and health survey in Jiangsu province. A total of 255,581 subjects (50.03% males and 49.97% females) enrolled in 82 school and 10 universities in Jiangsu. Weights and heights were obtained for each subject and its body mass index (BMI) was calculated using the Chinese Working Group on Obesity in China (CWGO).</p><p><b>RESULTS</b>Anthropometric measurement including bodyweight, height, BMI and bust were significantly different between males in urban compared to females living rural areas (P<0.001). The total prevalence of overweight and obesity was 12.4% and 5.7%. Males had a significantly higher rate than in female's student. The prevalence of overweight and obesity by age groups was (14.5%, 10.3%) at age 7-11 years, (11.2%, 6.8%) at age 12-14 years, (11.7%, 3.1%) at age 15-17 years, and (11.4%, 2.3%) at age 18-22 years. By regions; the highest prevalence of overweight obesity reported in Taizhou (10%, 14.2%), Xuzhou (9.4%, 12.5%), and Nanjing (9.2%, 15.6%), respectively.</p><p><b>CONCLUSION</b>The finding declares that overweight and obesity are important health problems among students in Jiangsu Province. Early intervention programme are needed to address this problems.</p>

Experiencia de caries en niños de 6 a 12 años de edad con obesidad exógena del Hospital General de México / Caries experience in children aged 1-12 years with exogenous obesity, at the General Hospital of Mexico

Objetivo: describir la experiencia de caries en una población infantil con obesidad exógena Método: Se realizó un estudio observacional, prospectivo, transversal y descriptivo. Fueron incluidos niños de 6 a 12 años de edad con obesidad exógena diagnosticados en el Servicio de la Clínica de Obesidad de la Unidad de Pediatría del Hospital General de México. El examen intraoral se realizó en el Servicio de Odonto-pediatría del propio hospital. Los índices utilizados fueron el ceod y CPOD, siguiendo los criterios de Klein y Palmer. Fueron acatados los principios éticos y legales de la Declaración de Helsinki para realizar investigación médica. El análisis estadístico fue de tipo descriptivo. Resultados: La población estuvo constituida por un total de 40 niños. La prevalencia de caries en esta población fue de 71 y 22% en la dentición temporal y permanente, respectivamente. El ceod promedio fue de 1.4, y el cPod , de 0.37 para la población total. conclusión: Los niños con obesidad exógena presentan un número reducido de dientes con experiencia de caries, inferior a la media nacional.

Objective:To describe the caries experience of children with exogenous obesity. Method:An observational, prospective, cross-sectional, descriptive study was conducted involving children aged 6 to 12 years with exogenous obesity, who were diagnosed at the Obesity Clinic of the Pediatrics Unit of the General Hospital of Mexico. Intraoral examination was performed at the hospital’s Department of Pediatric Dentistry. The indexes used were the dmft and DMFt, based on the criteria established by Klein and Palmer. The legal and ethical principles for medical research set forth in the Declaration of Helsinki were adhered to, and the statistical analysis was descriptive. results: The population comprised a total of 40 children, in whom caries prevalence in primary and permanent dentition was, respectively, 71 and 22%. For the total population, the average dmft was 1.4 and the DMFt was 0.37. conclusion: Children with exogenous obesity present a reduced number of teeth with caries experience, lower than the national average.
