Prevalence of thyroid nodule and relationship with physiological and psychosocial factors among adults in Zhejiang Province, China: a baseline survey of a cohort study.

BACKGROUND: Thyroid nodules have attracted much attention due to their high incidence and potential for malignant transformation. Compared with the clinical assessment and diagnosis of thyroid nodules, there are relatively few studies on the epidemiological risk factors for thyroid nodules. The aim of this study was to investigate the prevalence of thyroid nodule among adults in Zhejiang province and to explore their relationship with physiological and psychosocial factors. METHODS: The data used in this study were obtained from the baseline survey of the Zhejiang Provincial Cohort Study on Environment and Health. From June 2022 to December 2023, a total of 21,712 participants from five representative cities in Zhejiang were recruited for the baseline survey. Based on the inclusion and exclusion criteria, 15,595 adults were included in the analysis. The data were collected via self-report questionnaires and physical examinations. Multivariate logistic regression analysis was subsequently performed. RESULTS: The detection rate of thyroid nodules was 50.98% among adults in Zhejiang province. Age, gender, education level, BMI, tea and alcohol consumption all had a statistically significant association with thyroid nodules (p < 0.05). After adjusting for sociodemographic factors, results of logistic regression analysis showed that good life satisfaction (OR = 0.854, 95% CI: 0.780-0.934) had a lower risk of thyroid nodules, however, poor life satisfaction (OR = 1.406, 95% CI: 1.014-1.951), social isolation (OR = 1.294, 95% CI: 1.089-1.538) and a family history of thyroid nodules (OR = 1.334, 95% CI: 1.064-1.672) had a greater risk of thyroid nodules. CONCLUSION: The detection rate of thyroid nodules in adults of Zhejiang province was an increasing trend compared with that in previous years. In addition to the sensitive thyroid nodule screening technology, influencing factors mentioned in this study might also represent credible candidates for this increase. As variable influence factors, weight management, good interpersonal relationships and life satisfaction should be the focus of health interventions.

Psychological impacts of thermal ablation and conventional thyroidectomy in BTN patients: a prospective observational study.

BACKGROUND: Thermal ablation and conventional thyroidectomy are effective therapeutic methods for treating benign thyroid nodules (BTNs), but the psychological impacts of these methods in BTN patients are largely unknown. MATERIALS AND METHODS: This survey study prospectively enrolled patients who were admitted to our hospital between July 2021 and July 2022. The four validated scales were applied to quantify psychological distress and sleep quality at five points (the day admitted to the hospital, the day discharged from the hospital, and 1, 3, and 6 months after treatment). Participants who were diagnosed with BTNs and completed the questionnaires were ultimately enrolled and divided into thermal ablation and conventional thyroidectomy groups. A propensity score matching (PSM) cohort was subsequently developed to evaluate longitudinal and cross-sectional changes in psychological-related indicators. RESULTS: Among 548 eligible BTN patients, 460 patients completed all the questionnaires throughout the follow-up (response rate: 83.94%), including 368 (80.00%) patients who underwent thermal ablation and 92 (20.00%) patients who underwent conventional thyroidectomy. After PSM, a total of 342 patients were enrolled (256 patients underwent thermal ablation, and 86 patients underwent conventional thyroidectomy). The psychological-related indicators of patients in the thermal ablation group remained relatively stable during the 6-month follow-up, but patients in the conventional thyroidectomy group may have experienced greater anxiety and sleep quality concerns in the longitudinal assessment. Additionally, in the cross-sectional evaluation, the sleep quality of the thermal ablation group was also better than that of the conventional thyroidectomy group postoperatively. CONCLUSIONS: Thermal ablation is superior to conventional thyroidectomy for BTN patients in terms of psychological-related indicators.

A Long-Term Study Comparing the Quality of Life and Psychological Status of Patients with Highly Suspicious Thyroid Nodules ≤1 cm Undergoing Active Surveillance with Those Undergoing Immediate Surgery.

Background: Limited information is available on the long-term impact of active surveillance (AS) and immediate surgery (IS) on the quality of life (QoL) and psychological status of patients with highly suspicious subcentimeter thyroid nodules. Methods: A prospective study was conducted on 752 patients showing highly suspicious subcentimeter thyroid nodules, among whom 584 chose AS and 168 chose IS. All patients underwent at least two assessments regarding their QoL and psychological status, using three questionnaires: Thyroid Cancer-Specific Quality of Life (THYCA-QoL), Hospital Anxiety and Depression Scale (HADS), and European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Core Questionnaire (QLQ-C30). Propensity-score matching (PSM) at a ratio of 3:1 was utilized on patients in the AS and IS groups to mitigate selection bias (504 patients in the AS group and 168 in the IS group). Subsequently, the mixed linear model was used to analyze the QoL data. Results: The median time from the initial evaluation to the last follow-up in the AS and IS groups was 24.0 and 14.2 months, respectively. The AS group showed superior QoL outcomes compared to the IS group, mainly manifested in voice (p < 0.001), sympathetic (p = 0.008), throat/mouth (p < 0.001), and problems with scar (p < 0.001) domains, as per the THYCA-QoL questionnaire. Further, the EORTC QLQ-C30 questionnaire highlighted better outcomes in physical function (p = 0.029), role function (p < 0.001), social function (p < 0.001), global health status (p < 0.001), fatigue (p = 0.012), pain (p = 0.028), appetite loss (p = 0.017), and financial difficulties (p < 0.001). Compared to the initial assessment (1 week after surgery), the IS group showed progressive improvements in QoL, especially in voice (p = 0.024), throat/mouth (p < 0.001), physical function (p = 0.004), social function (p = 0.014), nausea and vomiting (p < 0.001), pain (p = 0.006), and appetite loss (p = 0.048) domains as per both questionnaires. Conclusion: Patients with highly suspicious subcentimeter thyroid nodules who choose IS tend to experience a poorer long-term QoL compared to those who choose AS. Although the situation may improve over time, certain issues might persist, making AS a favorable option for these patients.
