Overview

INTRODUCTION

Diabetes mellitus is a chronic disorder characterized by hyperglycemia because of insulin resistance, or inadequate insulin secretion. Diabetes mellitus is mainly classified as type 1 diabetes, type 2 diabetes, and gestational diabetes.1

Type 1 diabetes is caused by the loss of insulin-producing beta cells in the islets of Langerhans of the pancreas, resulting in insulin deficiency.2 Type 2 diabetes, on the other hand, is characterized by impaired insulin action or insufficient production of insulin by beta cells.2 Failure to produce insulin in Type 1 diabetes is immune-mediated where there is T cell-mediated loss of pancreatic beta cells.2 Whereas, the pathogenesis of type 2 diabetes involves a more complex interplay between genetic and environmental factors.2

Worldwide the prevalence of diabetes is increasing. Currently, a staggering 537 million adults aged between 20 to 79 years live with diabetes.3 By 2030, this number is expected to rise to 643 million, and by 2045, it will reach 783 million.3 Globally, the adult diabetes burden is 206 million in the Western Pacific, 90 million in Southeast Asia, 73 million in the Middle East and North Africa, 61 million in Europe, 51 million in North America and the Caribbean,  32 million in South and Central America and 24 million in Africa.3 Type 2 diabetes accounts for 90% of all diabetes cases.3

Diabetes is deemed a modern preventable pandemic.4 Globally, it is one of the top 10 causes of mortality worldwide.5 Diabetes incurs significant economic burden to the individual, family, healthcare system, and the country as a whole. The diabetes-related cost is estimated to increase globally by 2030.6  It may be possible to reduce the likelihood of developing the disease in the future by early identification of those at risk. Family health history (FHH) is a well-established non-modifiable risk factor for the development of diabetes in the family.7 Thence, health care providers and individuals can use knowledge of FHH of diabetes to determine genetic risk early and implement health promotion and disease prevention strategies. Moreover, FHH can be further integrated into health surveillance and tracking to strengthen the overall health system in improving health outcomes.

FHH in Diabetes

A family’s health history is an important component of assessing future risk of acquiring common chronic diseases.8 The presence of diabetes in the family is an important risk factor for the development of diabetes.7 FHH  is a strong predictor, independent and easily measurable risk factor for type 2 diabetes.9 Those with a family history of diabetes among first degree relatives are more likely to suffer from the condition than those without a family history of diabetes.10  FHH of diabetes has stronger effect on men than women.11  The chances of someone developing diabetes early are higher if they have FHH.12 In addition to type 2 diabetes, FHH is a major risk factor for gestational diabetes as well.

FHH information is critical for an individual, healthcare providers and overall health system. For healthcare providers, the knowledge of family health history of diabetes helps in risk assessment of developing type 2 diabetes for an individual and family. FHH is not just positively associated with type 2 diabetes as a risk factor but also with increased risk awareness and risk-reducing behaviors among type 2 diabetes.13 FHH of diabetes has proven to be a simple yet powerful tool in promoting healthy behaviors among those at risk.14   

 If an individual is aware about the risk related to FHH of diabetes, they can self-recognize and adopt healthier lifestyle changes as preventative measures for the development of type 2 diabetes. In a study, FHH-based preventative approaches have positively influenced those identified as at risk in making better lifestyle choices.15 It has also been shown that with knowledge of FHH it is possible to detect glycemic dysregulation among children so that prevention strategies could be implemented early.16

Evidence

COUNTRY SPECIFIC DATA ON PREVELANCE OF FHH

  1. Family history of diabetes and the risk of gestational diabetes mellitus in Iran: A systematic review and meta-analysis (IRAN)
    • The overall odds ratio of family history for developing GDM was estimated as 3.46 (95% CI: 2.80–4.27).
    • This meta-analysis study revealed that the family history of diabetes is an important risk factor for the gestational diabetes mellitus
  2. Family history of diabetes, lifestyle factors, and the 7‐year incident risk of type 2 diabetes mellitus in middle‐aged Japanese men and women. (JAPAN).1
    • Family history of diabetes was associated with the incident risk of diabetes,
    • The age and sex‐adjusted HR for type 2 diabetes in participants with a family history of diabetes was 1.82 (95% confidence interval 1.36–2.43) as compared with those without a family history of diabetes.
  3. Undiagnosed diabetes mellitus and associated factors among adults in Ethiopia: a systematic review and meta-analysis (ETHIOPIA).2
    • The pooled odds of developing diabetes mellitus among participants with a family history of diabetes mellitus were about 3.56 times higher than those without a family history of diabetes mellitus (OR = 3.56, 95% CI (2.23, 5.68)).
  4. Comprehensive risk profiles of family history and lifestyle and metabolic risk factors in relation to diabetes: A prospective cohort study. (CHINA)
    • FH was associated with 2.33-fold increased risk of diabetes, followed by high metabolic risk (1.90-fold) and high lifestyle risk (1.34-fold)
  5. Familial history of diabetes and clinical characteristics in Greek subjects with type 2 diabetes. (GREECE)
    • Excess maternal transmission of T2D in a sample of Greek diabetic patients
    • The presence of a family history of diabetes resulted to an early onset of the disease to the offspring.
