ABSTRACT
The prevalence of Chlamydia trachomatis varies between ethnic groups in The Netherlands. It is, however, unknown whether this is associated with specific serogroups. The objective of this study was to determine whether serogroup distribution is associated with ethnic origin in the region of The Hague, The Netherlands. Serogroups of 370 microbiologically confirmed C. trachomatis-positive samples were analysed. The samples were obtained from 247 women and 123 men between January and October 2008, of self-reported Dutch Caucasian, Dutch Antillean, Surinamese, N. African/Turkish or other descent. We observed a difference in serogroup distribution comparing Dutch Caucasian women to Dutch Antillean women (χ2 for distribution P = 0·035). Serogroup C was more common in Dutch Antillean women, whereas serogroup B was less common (P = 0·03). This difference was not observed for Dutch Antillean men. The observed difference in distribution of C. trachomatis serogroups between ethnic groups is relevant for further transmission studies.

The nutritional status of 478 children age 6-9 years students at four public schools of Araçuaí, state of Minas Gerais, Brazil, was evaluated. 403 children were from urban area and 75 from rural area, which corresponded to 21.9 percent and 3.9 percent of the counry population ar this age group. Nutritional status was assessed using measurernents of weigh and height according to the WHO recommendation and NCHS references. Stunring: height/age less than - 2 mean standard deviation; wasring: weight/leight less than - 2 mean standard deviation. The preva- lence of stunting and wasting in urban children was 2.5 percent and 7.9 percent, respectively; in rural children ir was 2.7 percent and 14.7 percent, respectively.
O estudo avaliou as condições nutricionais de 478 crianças de idade seis a nove anos, matriculadas em escolas públicas de Araçuaí, MG, no periodo de junho-julho de 1993. Da amostra estudada, 403 eram procedentes de zona urbana e 75 de zona rural correspondendo a 21,9 por cento e 3,9 por cento da população nesta faixa etária, dados de 1991 do IBGE. Para a classificação do estado nutricional, foram utilizados critérios recomendados pela OMS. Desnutrição crônica: índice altu- ra/idade menor que - 2 desvios-padrão da média; desnutrição aguda: peso/altura menor que - 2 desvios-padrão da média - stunting e wasting, respectivamente. Nas análises foram usados as referências do NCHS e os programas Epi Info e ANTHRO, e o coe de Atlanta (USA). A prevalência de desnutrição aguda e crônica em zona urbana foi de 2,5 por cento e 7,9 por cento respectivamente; em zona rural foi de 2,7 por cento e 14,7 por cento. Os índices de desnutrição crônica encontrados são bem superiores aos descritos para a região sudeste do país.
