To present a smoothed reference percentile and to show some characteristics of variables studied. Design. Descriptive, observational, cross-sectional study. Participants. Teenagers. Interventions. Waist circumference was measured in 8 236 adolescents aged 14 to 19 years old. Main outcome measures. Averages, standard deviation and prevalence of cardiovascular risk. Results. A national reference of waist circumference values is presented and the value corresponding to the 90 percentile is taken as cutoff level to identify adolescents with cardiovascular risk. Of the population studied, 12% were at risk. Those presenting higher risk were the male adolescents (12.1%), those living in urban areas (15.9%), in the Southern Coast (27.1...

ABSTRACT Objective To estimate the bacteriological quality of drinking water in Huancavelica, Cajamarca and Huánuco during 2012-2013 Material and Methods A cross-sectional study was conducted. Sampling was probabilistic, stratified and multistage. The sample included 706 households. The Readycult ® kit was used to assess the presence of total coliforms and E. coli. 100 mL of water used for food preparation was collected. The determination of residual chlorine was performed by semiquantitative analysis using Chlorine Test Reagent ®. It was established as the ideal residual chlorine concentration ≥0,5 mg/L. The statistical analysis considered the necessary weight for complex samples. We calculed percentages and chi square. The informed consent of the head of household is requested. It was defined as good bacteriological quality of water: water sample with adequate free chlorine, in th...
