The brand new survey is actually especially geared towards quantitatively examining magnesium and you may calcium on the diet plan, from food portion sizes and make use of from local regular water in the beverages and in food preparation.
There were twenty-a couple of questions about the consumption of milk and you can dairy, fish, beef, dough and you can grain, fresh fruit, make, nuts and foods and you may four questions towards accessibility alcohol, wines, drinking water and you can regular water situated drinks (coffee, teas, juices etc).
Brand new Department off Health-related Nutrition evaluated of the person intake from magnesium and you can calcium. Individual basal metabolic rate (BMR) try determined predicated on Schoefield et al. considering gender, decades, lbs and you may height . Contained in this people, the fresh every day total energy cost is projected becoming step 1.5* BMR. It contour was applied once the a sign of brand new bit proportions (brief, typical otherwise higher) to have principle meals included computations. To other food types, home actions including container, spoon, glass, slices an such like., and you may basic bit proportions based on Swedish conditions were used .
Investigation to have calcium and you can magnesium posts during the snacks had been taken from dining tables in the “Swedish Dining Investigation ft” on National Eating Management and you may out of firms analyses regarding mineral liquids and you will from real plain tap water analyses. For dinner edibles such as for example rice, folded oats, legumes (peas, kidney beans, lentils) and, spaghetti, brand new calculations have been made to your dead lbs, including an appropriate amount of plain tap water otherwise dairy, into planning. Brand new estimate away from dietary calcium and you may magnesium, derived from regional regular water was centered on drinking water analyses and you can anyone level of liquid made use of, in addition to preparing food and you can products.
Lab methods
Bloodstream is actually taken immediately following an instantly prompt, without alcoholic drinks the last 24 hours no smoking the fresh new past step 3 days, by the venipuncture and in Vacutainer Tubes. Analyses have been made from the Research off Clinical Biochemistry, Main Health from inside the Karlstad. Calcium and magnesium content in whole bloodstream, serum, strength and you may urine are determined by nuclear consumption spectrophotometry. Glycosylated haemoglobin, HbA1c, is determined by the fresh ion exchange HPLC method. Water products have been consumed in supplied bottles about research towards the early morning of visit to the medical heart and you can analysed to own magnesium and you can calcium supplements datingranking.net/craigslist-hookup/. The outcomes received when you look at the mg/l.
Analytics
Differences when considering organizations regarding proceeded variables were analysed playing with Student’s T-test and, getting variables evaluated just like the skewed, the fresh Mann-Whitney U-sample. Off categorical variables the newest chi-squared try was applied. Correlations had been computed having fun with Spearman’s review-correlation coefficient.
Multivariate linear regression are did to check on the cousin significance of things maybe contributing to the newest version within the risk basis account. Good stepwise procedure was applied, which circumstances maybe not significantly contributing was in fact omitted. Residuals was indeed seemed getting normality and you will exhibited zero unsettling provides.
Overall performance
Dining table 2 reveals detailed socio-monetary study. Age and you may sex was indeed similar regarding the groups. The person instructional peak are high on eastern municipality. The individuals on the western was actually residents throughout the local government a whole lot more ages compared to the fresh eastern.
Dining table step three shows fitness details of your participants. The prevalence of prior cardio issues, blood pressure level, Bmi and you can diabetes failed to differ between the teams, neither performed the usage therapy. Systolic blood pressure level are large, and smoking more widespread regarding the eastern compared to the west.
Laboratory variables try showed when you look at the table 4. The latest imply s-cholesterol levels is rather higher on western, since is the degree of s-LDL-cholesterol and you will LDL/HDL. Water given by the latest municipality was used from the twenty-four.5% about eastern town and 61.5% regarding the west, the remainder having fun with individual wells.
The complete stiffness regarding liquids, defined as the sum of calcium and you can magnesium, within the home water about several municipalities try demonstrated for the Figure step 1.
