Study of Diabetes' Risk Factors and Accelerated Aging According to Socio-economic Status in a Population From the North of France (PREVENDIAB)

Populations in precarious situations or with low socio-economic status have an increased risk of diabetes and accelerated aging. According to the population studied, the elements that can explain these health inequalities are not unequivocal and remain poorly known.

The north of France, particularly affected by socio-economic disparities, has a prevalence of diabetes among the highest in metropolitan France. This is why investigators want to study the clinical, biological, social and behavioural risk factors of the entry into diabetes and accelerated aging among a large population in the North of France.

This study aims to characterize the population (among which a majority (55%) suffers from precarious conditions) who come to carry out their health examination at the Pasteur Institute in Lille in order to study the risk factors to better explain these health inequalities.

This research consists of a main descriptive observational, cross-sectional study carried out on 2233 volunteers (main group) over 18 months, and a complementary analytical case-control study that will be offered to 216 participants (sub-group).

Study Overview

• Status: Completed
• Conditions: Diabetes; PreDiabetes
• Intervention / Treatment: Other: Biological analysis, Physical examination and Questionnaires; Other: Physical examination and Questionnaires

Detailed Description

Primary Objective : Assessment of Prevalence of Prediabetes and Diabetes by Socio-Economic Status

Primary efficacy endpoint : Fasting glucose value based on EPICES score :

Glycemia:

• Normal: fasting glucose ≤ 1g/l
• Prediabetes: fasting glucose >1 g/l and ≤1.25 g/l
• Diabetes: fasting glucose >1.25 g/l

EPICES score: quintiles of score distribution (Q1 to Q5)

Secondary Objectives specific to the main group:

• Characterize the population and analyze the risk factors (clinical, biological, socio-economic and behavioural) of diabetes and prediabetes in this population.
• Study the level of biological ageing and factors associated with accelerated ageing.
• Estimate the risk of (pre)diabetes and accelerated aging based on socio-economic profile.

Secondary Objectives specific to the sub-group:

• Assess the impact of economic, social and cultural capital on health in terms of diabetes and accelerated aging.
• Analyze the effect on diabetes and accelerated aging of the exposures assessed: body composition, physical activity, arterial rigidity, cognitive status, psychiatric disorders, fragility, pain.

Secondary endpoints specific to the main group: :

• Prevalence ratio of diabetes and prediabetes calculated for:

  • Clinical, paraclinical parameters (Oral examination, Muscle strength,Advanced glycation products) and anthropometric parameters (medical history, height, weight, BMI, Waist and hip circumference, Neck circumference, body composition measurement, Systolic and diastolic blood pressure, Unipedal stance test).
  • Biological (blood and genetic).
  • Behavioural/environmental predictors: (socio-economic status, physical activity(RICCI GAGNON), diet(HDI), quality of life (MQLI), stress-anxiety(PSS), toxic habits, fragility(FRIED) ).

• Assessment of the level of ageing

  • Biological Aging Marker: DNAmPhenoAge (DNA methylation phenotypic age)
  • Accelerated ageing: age regression DNAmPhenoAge on chronological age
  • Analysis of age-related parameters (inflammatory, renal, hormonal, body composition measurement, fragility, advanced glycation products, muscle strength) and correlation with methylation rate and DNAmPhenoAge.

• Prevalence ratio of (pre)diabetes and accelerated aging according to socio-economic status

  • Evaluation of (pre)diabetes: fasting blood sugar
  • Accelerated Aging Assessment: DNAm PhenoAge
  • Social Status Assessment: EPICES Q1 to Q5 Score
  • Assessment of economic status: Income level

Secondary endpoints specific to the subgroup:

• Risk (OR) of (pre)diabetes and accelerated aging according to social, economic, cultural and marital status

  • Evaluation of (pre)diabetes: fasting blood sugar
  • Accelerated Aging Assessment: DNAmPhenoAge

  • Socio-economic and cultural criteria

    • Social status (EPICES score)
    • Economic status (income)
    • Cultural status (semi-directive interview)
    • Professional status (educational level, socio-professional category, marital status)

• Risk (OR) of (pre)diabetes and accelerated aging for assessed exposures:

  • Evaluation of (pre)diabetes: fasting blood sugar
  • Accelerated Aging Assessment: DNAmPhenoAge

  • Exposure Assessment

    • Arterial Stiffness Index
    • Body composition (mineral density, lean mass, fat mass) (DEXA test)
    • Insomnia Severity Index (ISI)
    • Cognitive Status (MOCA)
    • Physical Activity (GPAQ Questionnaire)
    • Alcohol consumption (FACE)
    • Psychiatric disorders (MINI)
    • Fragility (REFS score)
    • Pain Scale (EVA)

• Study Type: Observational
• Enrollment (Actual): 2014

Study Population

Populations in precarious situations or with a low socioeconomic level have an increased risk of entering diabetes and aging accelerated. Depending on the populations studied, the elements that could explain these health inequalities are not unequivocal and are still badly known.

The Hauts-de-France region, particularly affected by disparities socio-economic, has one of the most prevalent diabetes high in the metropolis. This is why it's important to study the factors clinical, biological, social and behavioral risks of entry in diabetes and accelerated aging in a large population of North of France.

This study aims to characterize the population of the Centre's consultants of Health Examinations at the Institut Pasteur de Lille, of which a majority (55%) suffers from precarious conditions, in order to study the risk factors to better explain these health inequalities.
