But not, the general research is unconvincing. Small size and you can inadequate fat loss review are among the limits from the last epidemiological training, while the diet plan considering just one 24-hours recall was used so you can expect coronary attack incidence more an excellent 12-, step one 16-, 2 or 20-year period. cuatro It dieting investigations reduces the capability to to evolve to have practices away from other food stuffs otherwise diet that will give an explanation for inverse associations advertised. 11 To conquer this restriction, we addressed the latest hypothesis you to definitely higher potassium consumption decreases the chance from heart attack in an enormous cohort of males whom done an excellent in depth and you can verified semiquantitative dining frequency questionnaire on baseline and you will was in fact accompanied upwards to possess 8 age. On the other hand, i checked-out the associations ranging from threat of heart attack and consumption of fibre, magnesium, and you can calcium, that are correlated having intake off potassium that will getting related in order to threat of stroke.


The Health Professionals Follow-up Study began in 1986, when 51 529 health professionals 40 to 75 years old 12 completed a 131-item food-frequency questionnaire and provided information about medical history and lifestyle. Follow-up questionnaires were sent every 2 years to update information on potential risk factors and to identify newly diagnosed cases of stroke and other diseases. We excluded from analysis 1595 men who did not satisfy the a priori criteria of daily caloric intake between 800 and 4200 kcal and <70 blanks out of 131 total listed food items. In addition, we excluded men with prior diagnosis of myocardial infarction, angina, coronary artery surgery, stroke, transient ischemic attack, peripheral arterial disease, or diabetes. The average response rate for the 2-year follow-up cycles was >94%. Nonresponding participants not matched to the National Death Index were assumed to be alive.

Testing regarding Dieting and Other Visibility Details

The brand new 1986 questionnaire inquired about mediocre volume out-of consumption inside earlier in the day year away from specified portions regarding 131 food and rehearse from vitamin products medicine. Mineral calculations took into account the variety of morning meal cereal and you may vitamins claimed from the for each topic. We plus asked about entry to certain drugs from potassium and magnesium (aside from vitamins). I presumed the degree of potassium throughout these certain medications to help you be step one g/d and therefore off magnesium 0.3 grams/d, since the home sex hookup apps android elevators amounts weren’t questioned regarding questionnaire. I assessed the brand new legitimacy of your survey during the an arbitrary sample away from 127 men just who complete one or two step one-few days eating plan facts. 13 The latest correlations between the 2 examination off intake, energy-modified and you can corrected to own contained in this-people variation in the eating plan suggestions, have been 0.65 having potassium, 0.64 to possess dietary fiber, 0.66 getting magnesium, and you can 0.53 to possess calcium. As well as diet plan, inside the 1986, users were requested so you’re able to statement the usual systolic and you can diastolic blood stress and you will whether or not they got physician-identified hypertension. The new validity of these variables could have been noted in earlier times. 14


End circumstances had been deadly and you may nonfatal shots taking place between the return of baseline survey and you may January 31, 1994. Players reporting a case coronary attack towards a follow-up survey were required permission to review scientific ideas. Shots was indeed affirmed in the event the described as an everyday neurologic problem from abrupt or fast beginning, lasting ?1 day and you may attributable to good cerebrovascular enjoy. Strokes due to disease or neoplasia were excluded. Studies were presented by doctors lacking the knowledge of the fresh subjects’ chance basis status. Strokes was in fact subclassified according to the criteria of one’s National Questionnaire out-of Coronary attack while the because of ischemia (embolism otherwise thrombosis), subarachnoid hemorrhage, intracerebral hemorrhage, otherwise not familiar bring about. 15 If the zero details might possibly be acquired, shots was basically considered likely when they required hospitalization and you can was basically corroborated by the more info provided with letter otherwise interview.
