The association between adiposity measures and dyslipidemia has seldom been assessed in a multipopulational setting. 27 populations from Europe, Australia, New Zealand and Canada (WHO MONICA project) using health surveys conducted between 1990 and 1997 in adults aged 35-64 years (n = 40,480). Dyslipidemia was defined as the total/HDL cholesterol ratio >6 (men) and >5 (women). Overall prevalence of dyslipidemia was 25% in men and 23% in women. Logistic regression showed that dyslipidemia was strongly associated with body mass index (BMI) in men and with waist circumference (WC) in women, after adjusting for region, age and smoking. Among normal-weight men and women (BMI<25 kg/m(2)), an increase in the odds for being dyslipidemic was observed between lowest and highest WC quartiles (OR = 3.6, p < 0.001). Among obese men (BMI ≥ 30), the corresponding increase was smaller (OR = 1.2, p = 0.036). A similar weakening was observed among women. Classification tree analysis was performed to assign subjects into classes of risk for dyslipidemia. BMI thresholds (25.4 and 29.2 kg/m(2)) in men and WC thresholds (81.7 and 92.6 cm) in women came out at first stages. High WC (>84.8 cm) in normal-weight men, menopause in women and regular smoking further defined subgroups at increased risk. standard categories of BMI and WC, or their combinations, do not lead to optimal risk stratification for dyslipidemia in middle-age adults. Sex-specific adaptations are necessary, in particular by taking into account abdominal obesity in normal-weight men, post-menopausal age in women and regular smoking in both sexes.

Se analiza información biológico-pesquera de atunes y especies afines, proveniente de la actividad extractiva de 6 atuneras palangreras de bandera japonesa que con licencias de pesca operaron en aguas jurisdiccionales del Perú, entre noviembre 1992 y octubre 1993. Las faenas de pesca se efectuaron de 0° a 14°S y desde las 30 hasta las 380 mn de la costa. Las especies capturadas fueron: atún ojo grande o patudo (Thunnus obesus), atún aleta amarilla (T. albacares) y atún aleta larga (T. alalunga). La captura total de los 6 buques palangreros fue 2.052 t, el 64% fue atún, 27% tiburones, 3% pez espada y 6% otras especies como el dorado, mantas, rayas, etc. T. obesus presentó rango de tallas entre 50 y 260 cm; T. albacares entre 50 y 170 cm y T. alalunga entre 84 y 121 cm. El índice de abundancia relativa de T. obesus se estimó en 21,2 k por cada 100 anzuelos, mientras que para T. albacares fue 18,4 k por cada 100 anzuelos, con los mayores valores en otoño e invierno.
