Cadernos de Saúde Pública , 1997,
Abstract: In 1988, the General Directorate of Epidemiology and the Mexican Institute of Psychiatry conducted the first National Addiction Survey (ENA), providing regional and national data on alcohol, tobacco, and drug use. The ENA providing a subsample of women who have been pregnant at some time in their lives. There were 5,234 affirmative responses. Women were asked if they had suffered any of three adverse outcomes during their last pregnancy: spontaneous abortion, stillbirth, and congenital abnormalities. Prevalence of spontaneous abortion was 3.8%, stillbirth 1.2%, and congenital abnormalities 1.1 %. Multiple logistic-regression models were used to analyze the effect of alcohol consumption on these problems. Consumption during pregnancy was related only with the prevalence of congenital abnormalities, with prevalence odds of 3.4. Among habitual users during the last 12 months, oniy women in the highest use category showed an important relationship with the three problems mentioned. Follow-up studies on the Mexican population are recommended in order to obtain more conclusive findings.

Abstract: objective: to evaluate the association between invasive cervical cancer (cc) and high risk human papilloma virus (hr-hpv) (viral load and type 16), along with other gynecological and socioeconomic factors. material and methods: individually matched case-control study (215 women with invasive cc and 420 controls). the study population was recruited between 2000 and 2001. a set of variables traditionally linked with cc (gynecological and socioeconomic factors) and two variables related to hpv infection (viral load and type 16) were assessed. hybrid capture ii was used to detect hr-hpv dna. viral load was measured by light measurements expressed as relative light units (rlu) and they were categorized for analysis into four groups: negative (<1 rlu), low viral load (1-49 rlu), middle load (50-499 rlu) and high load (>499 rlu). the analysis included univariate, bivariate and multivariate techniques being the final step the estimation of odds ratios (or) by means of conditional logistic regression models. results: the probability of having invasive cc was 78 times higher in patients with infection of hr-hpv. risk increases with hpv type 16 (or=429.7) as compared with other types of hr-hpv (or=64.1). an important trend was observed with the increase of the viral load (from 46.6 with low viral load; to 250.7 with intermediate and 612.9 with high load). the findings also indicate significant diferences in the viral load between cases and controls according to age groups and hr-hpv types (16 versus others high risk types). finally, the partner-demographic and obstetrical variables related to the disease increased the risk of invasive cc. no association between cc and smoking was observed in this population. conclusions: this study helps in identifying women at higher risk of developing invasive cc as a subset of those patients infected with hr-hpv. the findings point strongly to the importance of the viral load in hr-hpv as a co-factor in the development of this disease. this

Abstract: objective. to determine the prevalence of lactation, the use of industrialized milk and weaning, and the factors related to lack of breast-feeding and early weaning in young infants of rural communities. material and methods. transversal study performed by last year medical students doing social service in 222 rural communities in mexico who applied structured interviews to 5 409 families with children younger than 1 year of age. results. the percentages of children who were never breast-fed were: in the north (n) 21.4%, in the center (c) 7.6% and in the south (s) 5.3%. children who were still being breast-fed, either exclusively or with mixed feeding by the third trimester were 35.6% (n), 67.6% (c) and 77.5% (s); in the second trimester, 67.2% (n), 40.9% (c) and 51.6% (s) had been weaned. in the n region it was observed that lack of breast-feeding was associated to the health personnel who attended delivery, mothers with six or more years of education and less than four children, dwellings with permanent material floors, two or more household commodities and a head of the family different from the father. early weaning was essentially associated to the same factors; additionally, to the child being taken care of by someone different from the mother, artificial lactation by parental decision or due to medical recommendation and the use of health services provided by social security or private physicians. conclusions. artificial lactation and early weaning are typical of small families, with high educational level of the mother, better living conditions and contact with medical personnel, especially in the n of the country. children are weaned before the second semester of life and it is therefore deemed necessary to implement health programs which promote breast-feeding and gradual weaning after the sixth month of life among the infant population of mexican rural communities.

Abstract: In this work the proximal analysis, physicochemical characterization, fatty acid profile and astaxanthin content of pigmented oil obtained by fermentation shrimp heads are presented. Lipids are the major components in the oil (95%). The saponification number is 178.62 mg KOH/g, iodine value 139.8 cg iodine/g, and the peroxide value was not detected. Density and viscosity were 0.92 mg/ml and 64 centipoises, respectively. The highest contents of fatty acids were linoleic (C18:2n6), oleic (C18:1n9) and palmitic (C16:0). Eicosapentaenoic acid (C20:5n3, EPA) and docosahexaenoic acid (C22:6n3, DHA) account for 9% of the total. The content of astaxanthin was 2.72 mg/g dry weight. The pigmented oil is a dietary source of nutrients with high value such as astaxanthin. En este trabajo se presenta el análisis proximal, caracterización físico-química, perfil de ácidos grasos y contenido de astaxantina en aceite pigmentado aislado por fermentación láctica de los residuos de camarón. Los lípidos son los componentes mayoritarios (95%). El índice de saponificación es 178.62 mg KOH/g, el de yodo 139.8 cg yodo/g, y los peróxidos no fueron detectados. La densidad y la viscosidad fueron de 0.92 mg/ml y 64 centipoises, respectivamente. Los ácidos grasos en mayor cantidad fueron el linoleico (C18:2n6), oleico (C18:1n9) y palmítico (C16:0). El ácido eicosapentaenoico (C20:5n3, EPA) y el docosahexaenoico (C22:6n3, DHA) suman el 9% del total. El contenido promedio de astaxantina fue de 2.72 mg/g base seca. El aceite pigmentado es una fuente dietética de nutrientes con alto valor como la astaxantina.
