Preprints with The Lancet is part of SSRN´s First Look, a place where journals identify content of interest prior to publication. Authors have opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early stage research papers that have not been peer-reviewed. The findings should not be used for clinical or public health decision making and should not be presented to a lay audience without highlighting that they are preliminary and have not been peer-reviewed.

Background: Pairs of spouses share common socio-economic, environmental and lifestyle factors. Multiple studies found that spousal diabetes status was related to diabetes prevalence. We explored the influence of spousal diabetes status and cardiovascular health metrics on risk of incident diabetes in a prospective cohort study.
Methods: The study participants were from a population-based cohort which called China Cardiometabolic Disease and Cancer Cohort and followed up for 3.6 years. 34821 non-diabetes individuals who have completed their own and spouse's glucose information were involved in the study. Diabetes was defined according to 2010 American Diabetes Association standard criteria.
Findings: Spousal diabetes diagnosis was associated with increased risk of incident diabetes (HR=1.246 95%CI: 1.111-1.397). Further, participants whose spouses with uncontrolled HbA1c level had higher risk of diabetes (HR=1.299 95%CI: 1.121-1.504) and the risk of diabetes disappeared in the participants whose spouses with controlled HbA1c level (HR=1.180 95%CI: 0.996-1.399). Moreover, individuals whose ideal cardiovascular health metrics (ICVHM) value was less than 4 were affected by their spouse's diabetes status, while individuals whose ICVHM value was 4 or more were not affected. Besides, those who had more components of ICVHMs than their spouses could avoid increase of diabetes risk associated with spouses’ diabetes diagnosis.
Interpretation: Spousal diabetes status with uncontrolled HbA1c level is an independent risk factor of individual diabetes, but strict management of spouse's HbA1c level and improving ICVHM profiles can prevent adverse effects of spousal diabetes status on diabetes risk.
