The aim of this paper is to make a descriptive analysis of Problematic Internet Use in college students, evaluating the possible association with health problems and addictive behaviors, as well as gender differences in user types. A total of 2,780 students participated in the study between 2011 and 2014, 29% of them being males (age 20.8 ± 5.1 years) and 71% females (age 20.3 ± 4.4 years). The prevalence of Problematic Internet Use (PIU) assessed by the Internet Addiction Test was 6.08%. Being under 21 years of age and studying for degrees in subjects other than the health sciences were associated factors with a higher frequency of this problem, no differences by gender or type of address were found. The results show a significant association with some health problems (migraines, back pain, excess weight or obesity, insufficient rest), psychological aspects (risk of eating disorders, risk of mental disorder, depression), family problems and discrimination; with no associations with substance use (alcohol, cannabis or tobacco) being found. Concerning the time of Internet use, weekly hours were significantly higher in women than in men, both the total time as for leisure. The analysis of the profile use in problematic users revealed that males are related to aspects of entertainment such as games or shopping online and females are related to aspects of socialization, such as chats and social networks.

The University stage gives rise to social and personal changes as the independence of the nuclear family and the increased responsibilities that are related to the acquisition and/or consolidation of life styles and habits that may determine the future health status. Inadequate nutrition, a high level of inactivity, risky sexual behavior, abuse of new technologies or starting consumption of legal and illegal drugs, are among the most significant risk behaviors in this phase. In order to know how to set and / or consolidate the habits and lifestyles in the university stage and health effects in the future, to born the uniHcos project. It is a dynamic cohort of university students who join the project during the first academic year and will be followed during their stay at college and working life. The follow-up will be biennially and for the capture and the information collection will be used on-line technologies. This paper aims to show the uniHcos project to the scientific community as well as present preliminary results found so far in the two cohorts established since 2011.
In the Huelva province, there is a geographical municipal distribution of cancer incidence with well-defined patterns for some specific tumour locations, with overall incidence rates very similar to those in the rest of Spain.
We explored the association between residence in an area polluted with metals and neurobehavioral performance in children aged 9 to 11. A cross-sectional study was conducted with thirty boys and thirty girls aged 9 to 11 from public schools in a heavily industrialized area, matched by age (±4 months) and gender with 15 boys and 15 girls from public schools in cities without relevant industrial activity. Neurobehavioral performance was assessed with the Behavioral Assessment and Research System. Linear regression models were used, adjusting for age, sex, social class and multimedia activities to predict each of the neurobehavioral outcome variables. No differences in neurobehavioral performance were found when all children with residence in areas with environmental exposure to metals were classified as exposed and the children from the other provinces as unexposed. However, when we compared children living <1 km from an industrial area with respect to those living more than 1 km away, significant differences were found. Children living <1 km away had lower scores on Finger Tapping (p = 0.03), Symbol-Digit (p = 0.07) and Continuous Performance (p = 0.02) than those living farther away. Our results support the hypothesis that residing close to an area with industrial activity (<1 km) is associated with deficits in neurobehavioral performance among children aged 9 to 11.
Background: Acidic urine pH is associated with rapid hydrolysis of N-glucuronide conjugates of aromatic amines into metabolites that may undergo metabolism in the bladder lumen to form mutagenic DNA adducts. We previously reported that consistently acidic urine was associated with increased bladder cancer risk in a hospital-based case-control study in Spain. Here, we conducted a separate study in northern New England to replicate these findings. Methods: In a large, population-based case-control study conducted in Maine, New Hampshire, and Vermont, we examined bladder cancer risk in relation to consistent urine pH, measured twice daily by participants over four consecutive days using dipsticks. In parallel, we collected spot urine samples and conducted laboratory measurements of urinary acidity using a pH meter. Unconditional logistic regression was used to estimate associations, adjusting for age, gender, race, Hispanic status, and state. Analyses were further stratified by smoking status. Results: Among 616 urothelial carcinoma cases and 897 controls, urine pH consistently≤6.0 was associated with increased bladder cancer risk (Odds Ratio(OR)=1.27; 95% Confidence Interval(CI)=1.02-1.57), with the effect limited to ever-smokers. These findings were supported by analyses of a spot urine, with statistically significant exposure-response relationships for bladder cancer risk overall (p-trend=5.1x10-3) and among ever-smokers (p-trend=1.2x10-3). Conclusions: Consistent with a previous study in Spain, our findings suggest that acidic urine pH is associated with increased bladder cancer risk. Impact: Our findings align with experimental results showing that acidic urine pH, which is partly modifiable by lifestyle factors, is linked to hydrolysis of acid-labile conjugates of carcinogenic aromatic amines.
Background: The association of meat intake with gastric adenocarcinoma is controversial. We examined the relation between white, red, and processed meat intake and gastric adenocarcinoma, considering doneness preference and cooking methods, by histological subtype and anatomical subsite. Methods: MCC-Spain is a multicase–control study that included 286 incident gastric adenocarcinoma cases and 2993 controls who answered a food-frequency questionnaire. The association of gastric adenocarcinoma with meat intake, doneness preference and cooking methods was assessed using binary multivariate logistic regression mixed models and a possible interaction with sex was considered. Multinomial logistic regression models were used to estimate risk by tumor subsite (cardia vs. non-cardia) and subtype (intestinal vs. diffuse). Sensitivity analyses were conducted comparing models with and without data on Helicobacter pylori infection. Results: The intake of red and processed meat increased gastric adenocarcinoma risk (OR for one serving/week increase (95% CI) = 1.11 (1.02;1.20) and 1.04 (1.00;1.08), respectively), specifically among men and for non-cardia and intestinal gastric adenocarcinoma. Those who consume well done white or red meat showed higher risk of non-cardia (white: RRR = 1.57 (1.14;2.16); red: RRR = 1.42 (1.00;2.02)) and intestinal tumors (white: RRR = 1.69 (1.10;2.59); red: RRR = 1.61 (1.02;2.53)) than those with a preference for rare/medium doneness. Stewing and griddling/barbequing red and white meat, and oven baking white meat, seemed to be the cooking methods with the greatest effect over gastric adenocarcinoma. The reported associations remained similar after considering Helicobacter pylori seropositivity. Conclusions: Reducing red and processed meat intake could decrease gastric adenocarcinoma risk, especially for intestinal and non-cardia tumors. Meat cooking practices could modify the risk of some gastric cancer subtypes.
Pulses such as peas, beans or lentils are one of the most complete foods at the nutritional level, however, it is one of the most often neglected in the diets of university students. Entrance to university translates to a major lifestyle change for many young people and the habits acquired or cemented at this time will remain into adulthood. The objective of this study is to analyze the association between personal/sociodemographic factors, dietary intake of other food groups and the consumption of pulses in first-year university students. This cross-sectional study is part of the UniHcos project, a multicenter study of multipurpose prospective cohorts in 11 Spanish universities. Data from 9862 university students was collected through an online self-questionnaire completed by all students who met the selection criteria and agreed to participate in the project during the 2011–2018 academic years. 75.8% of students presented an inadequate (≤ 2 times/week) consumption of pulses. Living outside the family home in either a student residence [OR = 0.76; 95%CI: (0.69 – 0.84)] or rental [OR = 0.81; 95%CI: (0.70 – 0.95)] decreased compliance with recommendations on the consumption of pulses. Low consumption of pulses is seemingly not restricted to a specific profile or dietary pattern among university students and no specific focus group for intervention can be identified. Policies promoting the consumption of pulses among the university population as a whole are necessary to increase compliance rates with the dietary recommendations.
