Association between gestational weight gain and risk of obesity in preadolescence: a longitudinal study (1997-2007) of 5125 children in Greece.

BACKGROUND: The present study aimed to investigate the association between gestational weight gain (GWG) and birth weight, as well as the body mass index (BMI) status, of children at the ages of 2 and 8 years. METHODS: Population-based data were obtained from a database of all 7-9-year-old Greek children who attended primary school during 1997-2007. The study sample consisted of 5125 children matched with their mothers, randomly selected according to region and place of residence, and equally distributed (approximately 500 per year) throughout the study period (1997-2007). A standardised questionnaire was applied; telephone interviews were carried out to collect maternal age, BMI status at the beginning and the end of pregnancy and GWG, birth weight of offspring and BMI status at the ages of 2 and 8 years, as well as several other pregnancy characteristics (e.g. pregnancy duration, gestational medical problems, maternal smoking and alcohol consumption habits, and lactation of offspring after pregnancy). RESULTS: Gestational weight gain was positively associated with the weight status of offspring at all three life stages studied: newborn (birth weight), infant (BMI) and child (BMI) [b = 0.008 (0.001), b = 0.053 (0.009) and b = 0.034 (0.007), respectively, all P < 0.001], after adjusting for maternal age at pregnancy (significant inverse predictor only at age 2 years). The same applied to excessive GWG, as defined by the Institute of Medicine guidelines. CONCLUSIONS: Excessive GWG was associated with a higher risk of greater infant size at birth and a higher BMI status at the ages of 2 and 8 years. Healthcare providers should encourage women to limit their GWG to the range indicated by the current guidelines.

Antioxidant foods consumption and childhood asthma and other allergic diseases: the Greek cohorts of the ISAAC II survey

BACKGROUND: Antioxidant intake changes have been implicated with the increase in asthma and allergies outcomes, but no clear association has been revealed. In this cross sectional study, the overall effect of antioxidants on asthma and allergic diseases was studied. METHODS: Data from the cohorts of the phase II ISAAC survey (2023 children 9-10 years old) in two metropolitan Greek cities were analysed. Using a semi-quantitative food frequency questionnaire, an Antioxidant Eating Index (AEI, range 0-6) was created with the pro-antioxidant (vegetables, fruits, fresh juice, fish) and the non-antioxidant (meat, burgers) food intake and was evaluated with allergic diseases. Higher values of the score suggest closer to an "antioxidant" and lesser to a "saturated fatty" diet. RESULTS: Prevalence of lifetime and current asthma, current rhinitis and sensitisation were higher in Thessaloniki compared to Athens. The AEI score of the entire cohort was 4.2 ± 1.2 (median 4.0) and was higher in Athens compared to Thessaloniki (4.3 ± 1.2 vs. 4.0 ± 1.2, p = 0.001) and in girls than boys (4.3 ± 1.1 vs. 4.0 ± 1.2, p = 0.001). AEI was inversely associated with lifetime asthma (OR: 0.87, 95%CI 0.77, 0.99) in either cities independently of other cofounders such as family history, sensitisation, exercise, house smoking, breast feeding, pet or dampness in houses. No association with other allergic disease or sensitisation was detected. CONCLUSION: Antioxidant foods seem to be a non-pharmacological, protective dietary pattern for asthma development in children irrespectively of atopy or heredity; AEI was a rough indicator and the role of antioxidants in allergic diseases is still under consideration

The association of sedentary lifestyle with childhood asthma. The role of nurse as educator

BACKGROUND: To provide a summary of the existing published knowledge on the association between sedentary lifestyle and childhood asthma. Twelve years ago, the first longitudinal studies carried out in children showed a relationship between physical activity and asthma. Several epidemiological studies confirmed these findings, with sedentary lifestyle predicting the onset of asthma. METHODS: A systematic review of epidemiological studies was conducted within the MEDLINE database. Epidemiological studies on children subjects, published in English were included in the review. A comprehensive literature search yielded 50 studies for further consideration. Following the application of the eligibility criteria, we identified 11 studies. RESULTS: A positive association and an excess risk of asthma during childhood were revealed to sedentary lifestyle. The findings proved the association between childhood asthma and sedentary lifestyle. The correlation between bronchial asthma and sedentary life during childhood and identifying whether preventable or treatable risk factors exist needs to be determined. Further research on the topic is essential for safer and standardised conclusions. Conclusions and practice implication: Asthma can be controlled when managed properly. The role of the nurse as an educator should establish and maintain a relationship with patients in order to help them manage their disease. The steps towards asthma management will help paediatric patients to guide their approach to the condition

Peripherally inserted central venous catheters: frequency of complications in premature newborn depends on the insertion site.

OBJECTIVE: The use of peripherally inserted central venous catheters (PICC lines) has reduced the mortality and morbidity of premature newborns. The usual sites of insertion are the veins in the upper arms but other locations are being used as well. STUDY DESIGN: To examine whether using the axillary vein as a site of insertion of a PICC line affects the frequency of complications. Our study has a clinical trial design. A total of 62 neonates that had a PICC line inserted were recruited and randomly divided equally in two groups: in Group A (mean birth weight, standard deviation (s.d.)=1353 (142) g), the PICC line was inserted through the axillary vein, and in Group B (birth weight=1308 (112) g), the PICC line was inserted in other sites further from the axillary vein. The outcomes measured were the total PICC line-related complications, the reason for removing the catheter, the number of total attempts until successful insertion and the mean duration of stay of the catheter. The likelihood of having an adverse outcome was assessed with Mantel-Haenszel odds ratio (OR). RESULTS: Premature neonates with axillary PICC lines were 12 times less likely to have line-related complications (inflammation, blockage, edema, infection) as compared with any other site of insertion (OR= 95%, confidence interval (CI)=0.10 (0.01 to 0.8)) and they were seven times more likely to have the PICC line removed because they achieved full enteral nutrition as compared with the other causes (OR 95%, confidence interval (CI)=10.35 (4.88 to 21.96)). There was no statistical difference between the two groups in the number of attempts until successful PICC line insertion (P=0.667) and the mean duration of stay of the PICC line (P=0.97). CONCLUSION: The use of the axillary vein as a site of insertion of a PICC line was correlated with significantly less complications in premature newborns as opposed to the other sites of insertion.

Breakfast consumption and meal frequency interaction with childhood obesity.

OBJECTIVES: Increased meal frequency and daily breakfast consumption have been inversely associated with childhood obesity. The purpose of the study was to examine the possible interaction effect between meal frequency and breakfast consumption on childhood obesity. METHODS: Seven hundred children (323 boys) aged 10-12 years were enrolled in this cross-sectional study. Several lifestyle, dietary and physical activity characteristics were recorded with food frequency and physical activity questionnaires. Body height and weight were measured and body mass index was calculated in order to classify children as overweight or obese (International Obesity Task Force classification). Multiple logistic regression analysis was used in order to evaluate the interaction between daily breakfast intake and more than three meals per day consumption with overweight or obesity. RESULTS: Of the children, 27.6% and 9.0% were overweight and obese, respectively. Moreover, 60.2% consumed three or more meals per day and 62.7% consumed breakfast in a regular daily basis. Children who consumed more than three meals per day and also consumed breakfast daily, were two times less likely to be overweight or obese (adjusted odds ratio: 0.49, 95% confidence interval: 0.27-0.88). CONCLUSION: A combined higher meal frequency and daily breakfast consumption dietary pattern may prevent overweight and obesity in children.

Association of extracurricular sports participation with obesity in Greek children.

AIM: Childhood obesity has become a modern epidemic with escalating rates. The aim of our study was the assessment of the association between extracurricular sports participation with the obesity status among Greek schoolchildren aged 10-12 years. METHODS: Seven-hundred children (323 boys) aged 10-12 years were evaluated through a standardized questionnaire. Several lifestyle, dietary and physical activity attributes were recorded. Children according to the median hours of participation in after-school structured physical activity were classified as participating for more or less than 3 hours per week. Body height and mass were measured and body mass index was calculated in order to classify children as overweight or obese according to IOTF classification. Multiple logistic regression analysis was used in order to evaluate the association between the participation of more than 3 hours per week in structured physical activity after school with overweight or obesity. RESULTS: A total of 48.9% of the boys and 31.8% of the girls were participating for more than 3 hours per week (P<0.001) in extracurricular sport activities. Moreover, 33.9 % of the boys and 22.1 % of the girls were classified as overweight and 9.4% of the boys and 8.6% of the girls as obese (P=0.006). Girls who participated in excess of 3 hours in extracurricular sport activities were 59% less likely to be overweight or obese than their non participating counterparts, adjusted for several confounders (adjusted OR: 0.41, 95% CI: 0.20-0.83). CONCLUSION: Participation in extracurricular sports activity is inversely related to overweight or obesity in 10-12 years old Greek girls.
