RESUMEN
BACKGROUND: Prodromal cardiac symptoms are warning signals preceding cardiac disease. Previous studies have shown some gender differences in prodromal symptoms as well as established risk factors for MI. This study aims to map possible gender differences in social factors and established risk factors preceding myocardial infarction (MI). METHODS: The study includes data of N = 213 middle-aged men and women, all diagnosed with myocardial infarction (ICD-10 I21.9) from the region of south-east Sweden. They answered a questionnaire at discharge from the cardiologic clinic and additional clinical data from medical records were merged from the National Swedeheart Register. RESULTS: The dominant prodromal symptom for both sexes were experience of chest pain at the onset of MI. The major gender differences were that significantly more females (p = 0.015) had a hyperlipidemia diagnose. Females also reported to have experienced higher stress load the year preceding myocardial infarction with serious life events (p = 0.019), strained economy (p = 0.003), and reports of sadness/depression (p < 0.001). Females reported higher perceived stress load than men (p = 0.006). Men had higher systolic blood pressure than women at hospital admission and a higher systolic- and diastolic blood pressure at discharge. CONCLUSIONS: Influences of the social environment, such as serious life events, strained economy, depression, stress, and sleep deprivation were stronger as potential risk factors for myocardial infarction in women than among men. Of the traditional risk factors only, hyperlipidemia was more frequent among women. These findings could contribute to a deeper understanding of diagnostic differences between gender, as well as a more gender-oriented cardiovascular preventive work.

BACKGROUND: The autoimmune process later leading to type 1 diabetes (T1D) seems to start very early in life. Different viruses have been suspected to contribute to the development of T1D, some already during pregnancy. As viruses may be hosted by animals and from them transferred to humans we decided to investigate if exposure to pets during pregnancy is related to later development of T1D. METHODS: ABIS (All Babies in Southeast Sweden)-is a prospective population-based cohort study of unselected children born in southeast Sweden between Oct first 1997 to Oct first 1999. Parents of 16 384 children answered a questionnaire within 3 days after birth including information about exposure to different pets. The ABIS registry has been connected to the National Registry of diagnosis and also the national Registry of Drug prescriptions so we know that 137 children have got T1D, and they were compared with the non-diabetic population. RESULTS: During pregnancy, 45.5% of the mothers had pet animals at home. Most common were cats (25.0%) and dogs (18.7%). Neither exposure to dogs (OR = 1.27, P = 0.23) or cats (OR = 0.81, P = 0.31) were associated to later T1D risks. However, exposure to hamsters increased the T1D risk (OR 4.21, P = 0.0007). In a multiple regression this association remained (P = 0.005) when adjusted for other possible risk factors. CONCLUSIONS: Exposure to hamster during pregnancy seems to increase the risk of T1D in the child. One possibility could be infection by virus hosted by the pet.

BACKGROUND: Many public health problems in modern society affect the gastrointestinal area. Knowledge of the disease occurrence in populations is better understood if viewed in a psychosocial context including indicators of the social environment where people spend their lives. The general aim of this study was to estimate the occurrence in the population and between sexes of common gastrointestinal conditions in two neighborhood cities representing two different social environments defined as a "white-collar" and a "blue-collar" city. METHODS: We conducted a retrospective register study using data of diagnosed gastrointestinal disorders (cumulative incidence rates) derived from an administrative health care register based on medical records assigned by the physicians at hospitals and primary care. RESULTS: Functional gastrointestinal diseases and peptic ulcers were more frequent in the white-collar city, while diagnoses in the gallbladder area were significantly more frequent in the blue-collar city. Functional dyspepsia, irritable bowel syndrome, and unspecified functional bowel diseases, and celiac disease, were more frequent among women while esophageal reflux, peptic ulcers, gastric and rectal cancers were more frequent among men regardless of social environment. CONCLUSIONS: Knowledge of the occurrence of gastrointestinal problems in populations is better understood if viewed in a context were the social environment is included. Indicators of the social environment should therefore also be considered in future studies of the occurrence of gastrointestinal problems.

BACKGROUND: In the Swedish welfare system, the prescription and price of antibiotics is regulated. Even so, socioeconomic circumstances might affect the consumption of antibiotics for children. AIM: This study aimed to investigate if socioeconomic differences in antibiotic prescriptions could be found for children aged 2-14 years, and to find predictors of antibiotic consumption in children, especially if morbidity or socioeconomic status in childhood may function as predictors. DESIGN & SETTING: Participants were from All Babies In Southeast Sweden (ABIS), a prospectively followed birth cohort (N = 17 055), born 1997-1999. Pharmaceutical data for a 10-year period, from 2005-2014 were used (the cohort were aged from 5-7, up to 14-16 years). Participation at the 5-year follow-up was 7443 children. All prescriptions from inpatient, outpatient, and primary care were included. National registries and parent reports were used to define socioeconomic data for all participants. Most children's infections were treated in primary healthcare centres. METHOD: Parents of included children completed questionnaires about child morbidity at birth and at intervals up to 12 years. Their answers, combined with public records and national registries, were entered into the ABIS database and analysed. The primary outcome measure was the number of antibiotic prescriptions for each participant during a follow-up period between 2005-2014. RESULTS: The most important predictor for antibiotic prescription in later childhood was parent-reported number of antibiotic-treated infections at age 2-5 years (odds ratio (OR) range 1.21 to 2.23, depending on income quintile; P<0.001). In the multivariate analysis, lower income and lower paternal education level were also significantly related to higher antibiotic prescription. CONCLUSION: Parent-reported antibiotic-treated infection at age 2-5 years predicted antibiotic consumption in later childhood. Swedish doctors are supposed to treat all patients individually and to follow official guidelines regarding antibiotics, to avoid antibiotics resistance. As socioeconomic factors are found to play a role, awareness is important to get unbiased treatment of all children.
RESUMEN
BACKGROUND: Although controversial, lower maternal intake of n-3 polyunsaturated fatty acid (PUFA) during pregnancy and lower levels of omega-3 PUFA in serum phospholipids during childhood have been related to obesity. The main source of omega-3 PUFA is fatty fish in the diet. OBJECTIVES: To assess the relationship between overweight/obesity and the intake of fatty fish in maternal diet during pregnancy and in children up to 8 years of age. METHODS: The prospective cohort All Children in South-East Sweden (ABIS) followed babies from birth to 8 years of age. A total of 6749 children at 5 years of age (boys 52.6%) and 3017 children at 8 years (boys 52.3%) participated. A "fatty-fish index" was constructed on the basis of self-reports of nutritional habits. RESULTS: The prevalence of overweight and obesity in children at 5 years were 12.9% and 4.2%, respectively. At 8 years, 12.2% of the children presented overweight and 2.3% obesity. Girls were more affected than boys by overweight/obesity. A higher fish index during pregnancy was not related to overweight/obesity in the children, whereas a higher fish index in the children during the first years of life was related to obesity at 5 and 8 years of age. This relationship disappeared in a multivariable analysis. Maternal body mass index (BMI), maternal education, maternal smoking during pregnancy, birth weight, and physical activity all remained related to overweight/obesity at both 5 and 8 years of age. CONCLUSION: No relationships were found between a lower intake of fatty fish in the diet, neither in mothers during pregnancy nor in early childhood, and increased risk of overweight/obesity.
RESUMEN
BACKGROUND: A relationship between overweight and obesity early in life and adolescence has been reported. The aim of this study was to track changes in overweight/obesity in children and to assess risk factors related to the persistence of overweight/obesity between 2.5 and 8 years. STUDY DESIGN: Children who participated in all three follow-ups at 2.5, 5 and 8 years in the prospective cohort All Children in Southeast Sweden (ABIS) (N = 2245, 52.1% boys and 47.9% girls) were classified as underweight, normal, overweight or with obesity, and changes within categories with age were related to risk factors for development of obesity in a multivariate analysis. RESULTS: The prevalence of overweight and obesity between 2.5 and 8 years was 11%-12% and 2%-3%, respectively. Children with normal weight remained in the same category over the years, 86% between 2.5 to 5 years and 87% between 5 and 8 years. Overweight and obesity at 5 and 8 years were positively related to each other (p < 0.0001 for both). High level of TV watching at 8 years and high maternal body mass index (BMI) when the child was 5 years were related to lower probability to a normalized ISO-BMI between 5 and 8 years of age (p < 0.05 for both). CONCLUSION: Children with ISO-BMI 18.5 to 24.9 remain in that range during the first 8 years of life. Children with overweight early in life gain weight and develop obesity, and children with obesity tend to remain with obesity up to 8 years of age. TV watching and high maternal BMI were related to lower probability to weight normalization between 5 and 8 years of age. A multidisciplinary approach to promote dietary and physical activity changes in the entire family should be used for the treatment and prevention of overweight and obesity in early childhood.
