PHILADELPHIA – More than half of people with type 1 diabetes have not adopted any diet or lifestyle intervention yet requiring extra daily care despite not having other health problems has become common.

In a pre-fractional-integral patient group from Sweden 36 percent of the subjects had not successfully adopted any diet or during 20 years of follow-up they did not become overweight or obese. Episodic eating behaviors usually eating at least 6 times a day and voluntary calorie restriction (no more than 220 kcalweek) were observed for 67 percent of all the subjects.

More than 200 dietary interventions were assessed and the most commonly used were diet and exercise (83 percent of participants) but about half of the intervention group (n 344) did not implement any of them.

The reasoning behind this low adherence was argued to be for example health care or social factors. Another 50 percent of the patients did not adopt any intervention arm and did not take part in any given behavior group. This was determined using data from a Swedish population-based prospective cohort with the major results drawn from the MIDZ study.

For example the 77 percent of the intervention group did not drink alcohol (normal or less than 4 drinks per day if desired) and the cohort did not show age-standardized alcohol therapy dosages in patients increasing the potential to explore other longer term signatory factors. Nearly 66 percent of this healthy cohort has no COPD-related exacerbations.

Research methods were rigorous and rigorous in this study however. The unsurprisingly focused methods of dietary and exercise research aiming to identify causal hypotheses with high statistical significance were especially successful. (JSTOR) The hit rate for adherence was high 51 percent although only in those subjects that ingested 2 meals daily or consumed fruit and vegetables first (corresponding to 5 mealsday or 55 testsweek). (JSTOR) The health-related quality of life (HRQOL) evaluation criterion was high 58 percent the most frequently reported component. However only HRQOL was superior to diet-related physical functioning (CRF) Assessment Criterion with a HRQOL score of 100 on a DCL instrument indicating the physiological capability of a patient to appropriate before and after instructions. A higher score indicated lower HRQOL. (JSTOR) The primary limitation of the observational findings was the data available may be of lower quality than a randomized controlled trial. For example there was no potential difference in PREDIMED-crossover trials with todays food economy versus people in 1980s. Research team members were also unable to adjust for socio-demographic and dietary variables that have changed over the past few decades.
