Impact of smoking on diabetes complications: a secondary analysis of the Korean National Health Insurance Service-health screening cohort (2002–2019): Seonmi Yeom, Youngran Yang; J Korean Acad Nurs 2025;55(2):222-235. Published online April 21, 2025; DOI: https://doi.org/10.4040/jkan.24109

Abstract PDF ePub: Purpose
This study aimed to examine the effects of smoking on the incidence of macrovascular and microvascular complications in patients with type 2 diabetes.
Methods
We analyzed 35,804 patients diagnosed with type 2 diabetes between 2004 and 2017 using the Korean National Health Insurance Service–National Health Screening Cohort (2002–2019). Smoking status was categorized into never, former, and current smoking, with further classification based on duration of smoking and daily smoking amount. We conducted survival analysis using a Cox proportional hazards model.
Results
Both former and current smokers had significantly elevated risks of macrovascular complications compared to non-smokers, with hazard ratios (HRs) of 1.60 (95% confidence interval [CI], 1.49–1.66) and 1.10 (95% CI, 1.08–1.17), respectively. Long-term smokers (over 30 years) had significantly higher risks of both macrovascular (HR, 1.35; 95% CI, 1.29–1.42) and microvascular complications (HR, 1.36; 95% CI, 1.30–1.42). Heavy smokers (over 2 packs/day) more frequently developed macrovascular (HR, 1.46; 95% CI, 1.30–1.64) and microvascular (HR, 1.78; 95% CI, 1.60–1.98) complications than never smokers. Notably, former smokers had increased risks of developing neuropathy (HR, 1.40; 95% CI, 1.31–1.49), nephropathy (HR, 1.27; 95% CI, 1.16–1.39), and retinopathy (HR, 1.49; 95% CI, 1.39–1.60).
Conclusion
Patients with type 2 diabetes and a history of smoking are at higher risk of developing macrovascular and microvascular complications. Smoking cessation, along with reducing smoking duration and amount, is crucial for lowering these risks.

Associations between the Frequency and Quantity of Heated Tobacco Product Use and Smoking Characteristics among Korean Smoking Adolescents: Haein Lee, Bo Gyeong Lee; J Korean Acad Nurs 2023;53(2):155-166. Published online April 30, 2023; DOI: https://doi.org/10.4040/jkan.22125

Purpose
Although heated tobacco product (HTP) use among adolescents is an emerging public health problem, little is known about the frequency and quantity of HTP use. Thus, we investigated the associations between the frequency and quantity of HTP use and smoking characteristics (i.e., combustible cigarette [CC] and electronic cigarette [EC] use, and attempts to quit smoking) among CC-smoking adolescents.
Methods
We analyzed nationally representative data from 2,470 Korean adolescents who were current CC smokers. To investigate our aim, we conducted multinomial logistic and logistic regression analyses.
Results
We found that daily and heavier CC users had greater likelihoods of more frequent and heavier HTP use. In addition, dual users of CCs and ECs were more likely to use HTPs more frequently and heavily than CC users who did not use ECs. Moreover, daily EC users had the highest risk of frequent and heavy HTP use. The frequency and quantity of HTP use were not associated with attempts to quit smoking. Compared to CC-only use, dual use of CCs and HTPs was not associated with quitting attempts, and triple use of CCs, ECs, and HTPs was associated with a lower likelihood of quitting attempts.
Conclusion
HTP use was less likely to displace CC use and promote attempts to quit smoking. Thus, strict regulations are required to prevent the promotion of HTPs as a substitute for CCs or as a means of quitting smoking. Additionally, health professionals should consider preventive interventions for HTP, as well as CC and EC use among adolescents.

Interorganizational Networks for Smoking Prevention and Cessation: A Blockmodeling Approach: Eun-Jun Park, Hyeongsu Kim, Kun Sei Lee, Junghee Cho, Jin Hyeong Kim, Ho Jin Jeong, Ji An Lee; J Korean Acad Nurs 2022;52(2):202-213. Published online April 30, 2022; DOI: https://doi.org/10.4040/jkan.21192

Abstract PDF: Purpose
This study examined characteristics and patterns of interorganizational networks for smoking prevention and cessation in Korea.
Methods
We surveyed two community health centers, ninety-five hospitals or clinics, ninety- two pharmacies, and sixty-five health welfare organizations in two districts of Seoul in 2020. Data on the organizations’ characteristics of smoking cessation and interorganizational activities for information sharing, client referral, and program collaboration were collected and analyzed using network statistics and blockmodeling.
Results
Network size was in the order of information sharing, client referral, and program collaboration networks. Network patterns for interorganizational activities on information sharing, client referral, and program collaboration among four organizations were similar between the two districts. Community health centers provided information and received clients from a majority of the organizations. Their interactions were not unidirectional but mutual with other organizations. Pharmacies were involved in information sharing with health welfare organizations and client referrals to hospitals or clinics. Health welfare organizations were primarily connected with the community health centers for client referrals and program collaboration.
Conclusion
A community health center is the lead agency in interorganizational activities for smoking prevention and cessation. However, hospitals or clinics, pharmacies, and health welfare organizations also participate in interorganizational networks for smoking prevention and cessation with diverse roles. This study would be evidence for developing future interorganizational networks for smoking prevention and cessation.
