AIMS/HYPOTHESIS Low birthweight is associated with a high risk of diabetes, but there are no reports discussing birthweight and pancreatic tissues in humans. The purpose of this study was to examine the correlation between birthweight and beta and alpha cell mass in humans. METHODS Sixty-four Japanese adults with and without diabetes who underwent pancreatectomy and were able to recall their weight history including birthweight were included. Pancreatic tissues were stained for insulin and glucagon, and fractional beta cell area (BCA) and alpha cell area (ACA) were quantified. Islet size and density and beta cell replication were also quantified and their associations with birthweight were evaluated. RESULTS In participants without diabetes, there was a weak positive correlation between birthweight and BCA (R = 0.34, p = 0.03). The group with a history of childhood obesity, but not the group with a history of obesity in adulthood only, showed higher BCA compared with those without a history of obesity (1.78 ± 0.74% vs 0.99 ± 0.53%, p = 0.01), and the correlation coefficient between birthweight and BCA increased after excluding those with a history of childhood obesity (R = 0.51, p < 0.01). In those with diabetes, there was no correlation between birthweight and BCA. No correlation was found between birthweight and ACA in either those with or without diabetes. CONCLUSIONS/INTERPRETATION Birthweight and beta, but not alpha, cell mass are positively correlated in non-diabetic adults, and a history of childhood obesity may affect beta cell mass.

日本成年人出生体重和儿童肥胖史与β细胞量的关联。

目的/假设低出生体重与糖尿病的高风险相关,但没有关于人类出生体重和胰腺组织的报告。这项研究的目的是检查出生体重与人类 β 和 α 细胞质量之间的相关性。方法 64 名患有或未患有糖尿病的日本成年人接受了胰腺切除术,并且能够回忆起他们的体重史,包括出生体重。对胰腺组织进行胰岛素和胰高血糖素染色,并对部分 β 细胞面积 (BCA) 和 α 细胞面积 (ACA) 进行量化。还量化了胰岛大小和密度以及 β 细胞复制,并评估了它们与出生体重的关联。结果 在没有糖尿病的参与者中,出生体重和 BCA 之间存在微弱的正相关(R = 0.34,p = 0.03)。与没有肥胖病史的人相比,有儿童肥胖病史的组而不是仅在成年期有肥胖病史的组显示出更高的 BCA(1.78 ± 0.74% vs 0.99 ± 0.53%,p = 0.01),并且排除有儿童肥胖史的人后,出生体重和 BCA 之间的相关系数增加(R = 0.51,p < 0.01)。在糖尿病患者中,出生体重和 BCA 之间没有相关性。在有或没有糖尿病的人中,出生体重和 ACA 之间没有发现相关性。结论/解释 在非糖尿病成人中,出生体重和 β(而非 α)细胞量呈正相关,儿童肥胖病史可能会影响 β 细胞量。图形概要。与没有肥胖史的人相比,BCA 显示出更高的 BCA(1.78 ± 0.74% vs 0.99 ± 0.53%,p = 0.01),并且在排除有儿童肥胖史的人后,出生体重和 BCA 之间的相关系数增加(R = 0.51, p < 0.01)。在糖尿病患者中,出生体重和 BCA 之间没有相关性。在有或没有糖尿病的人中,出生体重和 ACA 之间没有发现相关性。结论/解释 在非糖尿病成人中,出生体重和 β(而非 α)细胞量呈正相关,儿童肥胖病史可能会影响 β 细胞量。图形概要。与没有肥胖史的人相比,BCA 显示出更高的 BCA(1.78 ± 0.74% vs 0.99 ± 0.53%,p = 0.01),并且在排除有儿童肥胖史的人后,出生体重和 BCA 之间的相关系数增加(R = 0.51, p < 0.01)。在糖尿病患者中,出生体重和 BCA 之间没有相关性。在有或没有糖尿病的人中,出生体重和 ACA 之间没有发现相关性。结论/解释 在非糖尿病成人中,出生体重和 β(而非 α)细胞量呈正相关,儿童肥胖病史可能会影响 β 细胞量。图形概要。排除有儿童肥胖史的人,出生体重与BCA的相关系数增加(R = 0.51,p < 0.01)。在糖尿病患者中,出生体重和 BCA 之间没有相关性。在有或没有糖尿病的人中,出生体重和 ACA 之间没有发现相关性。结论/解释 在非糖尿病成人中,出生体重和 β(而非 α)细胞量呈正相关,儿童肥胖病史可能会影响 β 细胞量。图形概要。排除有儿童肥胖史的人,出生体重与BCA的相关系数增加(R = 0.51,p < 0.01)。在糖尿病患者中,出生体重和 BCA 之间没有相关性。在有或没有糖尿病的人中,出生体重和 ACA 之间没有发现相关性。结论/解释 在非糖尿病成人中,出生体重和 β(而非 α)细胞量呈正相关,儿童肥胖病史可能会影响 β 细胞量。图形概要。儿童肥胖病史可能会影响β细胞量。图形概要。儿童肥胖病史可能会影响β细胞量。图形概要。
