Lead exposure and physical frailty in patients with type 2 diabetes mellitus: cross-sectional results from the METAL study.
Purpose: Chronic lead exposure continues to be a global environmental concern. Previous studies reported high levels of lead exposure in people with diabetes. Frailty is one of the vital comorbidities of type 2 diabetes mellitus (T2DM); however, researchers have not determined whether lead exposure is a risk factor for frailty in people with T2DM.
Methods: This cross-sectional study explored the association between blood lead levels and frailty in a Shanghai diabetic population cohort. Individuals who met ≥3 of 5 predefined criteria (weight loss, exhaustion, low physical activity, slow walking speed and low grip strength) were defined as frailty.
Results: A total of 884 participants with T2DM (50.6% men, mean age 70.6 ± 7.4 years) were included. Among them, 147 (16.6%) patients were frail, and the median (interquartile range) concentration of blood lead was 16.0 µg/L (12.0-23.0). Compared with the participants within the lowest quartile of serum lead, positive associations of the 2nd and 4th lead quartiles with frailty were observed (OR, 95% CI; 1.70 1.01-2.84 and 1.72 1.03-2.88, respectively) after adjusting for age, sex and body mass index (BMI). After further adjustment for drinking status, smoking status, diet, education, blood pressure, triglycerides and glycosylated hemoglobin, the associations of serum lead with frailty were still significant for the 4th and 2nd-4th quartiles of lead (1.71, 1.01-2.91 and 1.57, 1.02-2.41, respectively). In the subgroup analyses, we found positive associations of serum lead with frailty in elderly individuals (1.77, 1.13-2.79), those with obesity (2.14, 1.02-4.51), those with unhealthy diets (2.52, 1.26-5.04), and those without hyperlipidemia (2.09, 1.12-3.88), although the interactions were not statistically significant (P for interaction all >0.05).
Conclusion: This work provides evidence of an association between chronic lead exposure and physical frailty in a diabetic population in a Chinese cohort. Future prospective and mechanistic studies are warranted to confirm our findings.
期刊介绍：
Well-established as a major journal in today’s rapidly advancing experimental and clinical research areas, Endocrine publishes original articles devoted to basic (including molecular, cellular and physiological studies), translational and clinical research in all the different fields of endocrinology and metabolism. Articles will be accepted based on peer-reviews, priority, and editorial decision. Invited reviews, mini-reviews and viewpoints on relevant pathophysiological and clinical topics, as well as Editorials on articles appearing in the Journal, are published. Unsolicited Editorials will be evaluated by the editorial team. Outcomes of scientific meetings, as well as guidelines and position statements, may be submitted. The Journal also considers special feature articles in the field of endocrine genetics and epigenetics, as well as articles devoted to novel methods and techniques in endocrinology.
Endocrine covers controversial, clinical endocrine issues. Meta-analyses on endocrine and metabolic topics are also accepted. Descriptions of single clinical cases and/or small patients studies are not published unless of exceptional interest. However, reports of novel imaging studies and endocrine side effects in single patients may be considered. Research letters and letters to the editor related or unrelated to recently published articles can be submitted.
Endocrine covers leading topics in endocrinology such as neuroendocrinology, pituitary and hypothalamic peptides, thyroid physiological and clinical aspects, bone and mineral metabolism and osteoporosis, obesity, lipid and energy metabolism and food intake control, insulin, Type 1 and Type 2 diabetes, hormones of male and female reproduction, adrenal diseases pediatric and geriatric endocrinology, endocrine hypertension and endocrine oncology.
