dos. Materials and techniques
Data were collected using the WBQ tool from in the area of Athens, Greece from 473 individuals aged 16–86 (42 ± 18 years) (221 males) in summer and from 511 individuals aged 16–86 (38 ± 20 years) (245 males) in winter, stratified by age and sex according to the Hellenic Statistical Authority . All volunteers were informed on the objectives of the study and the procedures involved and signed an informed consent. The retrieved data were confidential, and the study followed the ethical considerations provided by The Code of Ethics of the World Medical Association (Declaration of Helsinki). The WBQ incorporates a semi-quantitative food frequency questionnaire validated to record energy intake against three-day diaries (p < 0.001)>
Specifically, new WBQ will bring: (A) data into character of your own participant; (B) tape of use toward period of the earlier in the day few days away from good and you may liquid restaurants, h2o otherwise products out-of a partial-decimal food regularity survey (FFQ) from 58 products validated to possess quoting energy intake in addition to additional sugar and you will honey which is placed into products; and you may (C) estimation away from physical exercise due to their the brand new Globally Physical exercise Questionnaire (IPAQ) , and therefore ideas time of physical working out at the about three pastime account (serious, average, lightweight do it) otherwise sedentary requirements. The fresh new IPAQ might have been verified in past times since the a cross-national appliance having tape physical exercise [20,21,22] and guess opportunity expense.
The power and you can h2o content from recorded dinners and you may drinks are analyzed with the Diet plan Analysis And additionally (Wadsworth Posting Co Inc., Belmont, California, USA), hence spends structure research about USDA National Nutrient Database and you may chosen Greek meals (we.age., mousakas, pastitsio, Greek yoghurt, lentiles kidney beans soups, numerous Greek pies, souvlaki, overflowing tomatoes) . Centered on complete times intake and effort expenses, energy harmony was examined as well.
Within study, “drinks” makes reference to fresh fruit juices otherwise packaged liquid 100% rather than sugar posts, sugar-sweet tasting drinks (SSDs) (fresh fruit nectar which have sugar, sodas having sugar and effort/isotonic https://kissbrides.com/brazilian-women/porto-seguro/ drinks), low-calorie sodas, beverage and you can herbal infusions, milk (all sorts of whole milk, delicious chocolate dairy and cocoa drink), milkshake and you will sherbets, coffee and coffee drinks, and you can alcoholic beverages (beer, wines and all of type of alcoholic drinks). “Take in energy intake (DEI)” means times intake away from products “total times intake (TEI)” to help you time consumption out-of the supplies and you will “energy consumption off snacks” so you can times intake from solid and you can fluid food (e.g., soups). The fresh new share of beverages organizations in order to full opportunity intake (analysis off Malisova et al. 2013), exhibited as total water intake (TWI), i.age., h2o of drinks, h2o, solid and you will water snacks so that as take in water intake (DWI), i.elizabeth., water of products and h2o.
step three. Mathematical Research
Results are presented while the suggest ± sd to the generally speaking delivered variables and you may median (P25–P75) toward skewed of those. Normality is actually looked at utilising the opportunities–chances plot (P–P patch) and you may histograms. Differences when considering folks concerning your total opportunity intake, energy regarding beverages, energy out-of products, times expenses, time balance, drinking habits, water out of drinking water and products, liquid of beverages, h2o out of h2o, liquid of products, liquid losses and h2o balance was in fact analyzed towards the separate test t-take to to the generally speaking distributed details and also the Mann-Whittney You-shot on the skewed of these. Likewise, differences between new four quartiles of energy off beverages was in fact assessed to the you to definitely-way ANOVA F-try on usually delivered details while the Kruskal-Wallis H Test on skewed of those. Importance height is lay on 5%. Correlations amongst the contribution of drinks to help you drinking habits during the relatives in order to time during the winter and you will june was checked of the Pearson’s otherwise Spearman’s correlation coefficients having generally speaking distributed or skewed parameters. All of the statistical analyses did having fun with PASW Analytics 18 (SPSS Inc, il, IL, USA).
