    Title:

    A proposal - a measure in the modern concept of type-2 diabetes (T2DM) prevention focused on

    increasing cardiorespiratory fitness and macronutrient content of diet at high-risk obese adult and

    elderly population

    Author:Simovska Vera., MD., PhD.

    Institution:HEPA Macedonia National organization for the promotion of health-enhancing physical activity, Skopje,

    Macedonia, FYR

    Introduction/Aims:Obesity is known to lead to many health issues: metabolic complications that increase the risk for

    development of type-2 diabetes (T2DM) in adult and elderly population (elderly diabetes),

    cardiovascular diseases, and joint public health problems.

    Our objectives were to promote preventive-therapeutic programmes with a proposal - a measure forincreasing cardiorespiratory fitness (VO2max) and macronutrient content of diets intended for obese adult

    and elderly population with abdominal fat distribution who are asymptomatic, but at high-risk for

    development of T2DM.

    Method:Within the 7 week clinically controlled trial at a group of 82 middle-aged subjects (24-65 years) devided

    into two intervention groups: physical activity and diet (PAD) and diet (D) with mean BMI = 32.6 kg/m2

    and present

    pre-diabetes (a fasting plasma glucose of 100 140 mg/dl after an overnight fast), the following wereapplied: individually dosed, programmed physical activity (PA) and moderate energy reduced

    diet,performed into two phases.

    A proposal - a measure for increasing VO2max with aim to reduce T2DM risk included: 30 minutes daily

    in 3 bouts of ten minutes or 2 bouts of 15 minutes of moderate-intensity physical activity (3.0 - 4.5 METs

    for male; 2.1 - 4.2 METs for female) with training pulse of 50 - 59% heart rate maximum reserve in the

    first phase or 45 - 60 minutes, 3 times a week of moderate to vigorous intensity physical activity (4.5 - 7.0

    METs for male; 4.2 - 6.3 METs for female) with training pulse of 60% heart rate maximum reserve in

    the second phase. Muscle strength and flexibility exercise was included twice a week.In the first phase of the research, moderate energy reduced diet had a character of "a temporary" diet of

    1200kcal/d with a specific macronutrient content: CHO=50.1% (Poly CH=47.2%), P=25.7% and

    F=25.8% of total energy intake,

    a specific relation among SFA, MUFA, PUFA, a low atherogenic potential (AI < 15) and vitamin-mineral

    supplementation. The second phase was the increased energetic value of the diet for 200 kcal/d with nextcontent: CHO=54.1% (Poly CH=58.9%), P=26% and F=21.1% of total energy intake.

    Conclusion:

    T2DM can be prevented in high-risk truncal obese adult and elderly population using increasing VO 2maxand specific macronutrient content of diets in accordance with our a proposal - a measure.

    The question of an integrated T2DM and CVD risk

    management at high risk obese subjects is important scientific

    problem and every new result opens new questions. It,s

    becoming increasingly clear that physical activity may be a

    therapeutical tool in a variety of subjects with, or at risk for

    T2DM and CVD.

    At present, clinical researches of different branch of medicine,

    exercise scientists, pharmacists, nutritionists, psychiatrists,

    sociologists and many others are surprised with the fact thatfinally healing is achieved at every seventh of hundred obese

    individuals with average/ increased and high risk for T2DM,

    CVD and other NCD.

    Overall scientific results including our data are additional

    argument that any other preventive-therapeutic treatment isnot possible to be applied as alteration for physical activity in

    an integrated T2DM and CVD risk management.

    INTRODUCTION

    Numerous epidemiological, genetically and molecular

    studies at different population worldwide confirmed that obesity isassociated with metabolic complications that increase the risk forT2DM, CVD and other NCD. The complex of multifactor phenotype isdetermined of interaction between:

    Behavior factors: energy intake and expenditure defined

    as affects on body fat mass

    Genetics variations (hereditary predisposition)

    Different biological factors: sex, vulnerable ages related

    to increased weight, ethnically and hormone activity

    Community situation

    1. To promote preventive-therapeutic programmes with a

    proposal-a measure for macronutrient content of diets and

    increasing cardiorespiratory fitness (VO2max) intended fortruncal obese subjects who are asymptomatic, but at high-risk for T2DM and CVD.

    2. To develop a method for prescription of programmed physical

    activity (PA) in accordance with individual performing theexercise and biological characteristics of subjects.

    3. To estimate the efficiency of the method on T2DM and CVDrisk reduction at abdominal obese subjects included in 7wkrandomized controlled trial.

    4. To construct a new index as mathematical model for predictingthe effects of non-pharmacological therapies at obesepopulation on average/increased and high risk for CVD andother NCD.

    MATERIAL AND METHOD:

    Within the clinically controlled trial was examined 45 middle-aged

    subjects devided into two intervention groups: PAD (physical activity

    and diet) and group D (diet) with mean BMI=32.6kg/m2 and present

    pre-diabetes (a fasting plasma glucose of 100-140mg/dl after an

    overnight fast).

    In group PAD the following were applied: moderate energy reduced

    diet and individually dosed, programmed physical activity (PA)

    performed into two phases.

    In the first phase of the research, a diet had a character of

    "a temporary" diet of 1200kcal/d with a specific macronutrient content:

    CH=50.1% (Poly CH = 47.2 %), P=25.7% and F=25.8% of total EI, a

    specific relation among SFA, MUFA, PUFA, a low atherogenic potential

    METHODS FOR PRESCRIPTION OF PHYSICAL ACTIVITY

    1. The basic criterion for patient selection in four groups ofphysical activity levels (PALs) was initial level of VO2maxexpressed in term of metabolic equivalents (METs).

    2. MET was calculated by the equation:

    VO2max (ml-1kg-1min-1)/3.5

    3. The method for modeling of programmed PA

    was established using the classification for VO2max(WHO, 1974).

    4. Training pulse (% HR max reserve) was calculated using

    equation by Karvonen Martin (Tab. 1).

    5. Classification for intensity of PA i.e. physical work wasexpressed as energy expenditure in term of METs (Tab. 2).

    6. Using tables for gross energy expenditure of various PA withknown energy cost (METs) were chosen different type of PA inaccordance with initial level of VO

    2max (METs) (Poster for

    Physical Activity and Health).

    LOGISTIC REGRESSION

    Logistic regression was implement with aim to predict those regressors which withtheir values as final result are giving a probability for selecting for either the groupPAD or the group D.

    In the analysis are included 50 independent variables, and as outcome variable wasthe group which signified the type of therapeutically treatment among our patients.

    The first model of logistic regression shown in a form of equation gives dividingthe patients in one of the groups depending on the value of the exponent (Exp. B)which is interpreted in term of relative risk (RR).

    As a result is the prediction of 94.87%.

    The result shows that the regressors are separated like the following 6 variables:body mass index-BMIkg/m2, cardio respiratory capacity VO2maxOPV (ml

    -1kg-1min-1) as expected average value, indicial level of hemoglobin-Hbin, skin fold thickness

    upon m.biceps (SFT-Bin), level of VO2max using by WHO classification and energyexpenditure (kcal/h) during PA with intensity of 50% HRmax reserve (VO2max).Logistic model in form of equation is:

    lnRR = 108.2588 1.7689 x DKN-B in + 1.7087 x BMI in+ 0.3993 x Hb in

    - 2.9423 x VO2max (OPV)- 10.5402 x WHO in+ 0.0770 x 50%kcal/h

    This method for prescription and modeling of programmedphysical activity is proposed since the relative risk is upper than 1

    (RR>1).

    The second model of the logistic regression shows the efficacy of

    treatment and that is patients of PAD group are increasing the levelof HDL-C.

    In this analysis are included 47 variables. As outcome variable is

    HDL-C in the final phase of treatment. It's the most significant leading

    change, confirmed mathematically with the equation:lnRR=11.834710.545 HDL-C fin

    The results of this clinical trial are pointing to the significant of the

    discovery of this variables.

    The aim is the dividing of the group of risk patients with the

    possibility developing complications related to obesity.

    CONCLUSION

    Using our method for prescription and modelling of programmed

    physical activity (PA) were achieved:

    - significant greater reduction on T2DM and CVD risk in FAD (physical

    activity and diet) group than those in D (diet) group

    - enlarged types of PA- enabled safe performance and

    - avoid the risk for cardiovascular events during the individually and

    group,s exercising.

    Broader application of the method for prescription and modelling of programPA on field is proposed at subjects and groups with:

    - low level of cardiorespiratory fitness: 20 ml/kg/min VO2 for male

    and 14.2 ml/kg/min VO2 for female

    - increased/high risk for main NCD- insulin resistance/Sy X

    - FAI%, sport,s recreation.
