Summary:
Study Participants: In our study, we focus on smokers who self-report a "current smoking" status or smoking cessation less than 6 months. This trial is a sub-trial of "Impact of Multi-Component Interventions on a High-Risk COPD population" (Protocol ID: CAMS\&PUMC-IEC-2024-040). All smokers in this trial are either from the high-risk COPD population (defined by COPD-SQ score≥16) .

Intervention: For study participants in the intervention arm, we will ask them to finish an online COPD-SQ questionnaire with notification of his or her COPD high risk. For those whose score of COPD-SQ ≥ 16, we will provide a face-to-face survey, simple physical examination, pulmonary function tests, and provide a multi-component intervention at baseline. For smokers in the intervention arm, we provide a digital health intervention program, NicQuit, to whom could familiarly use intelligent mobile phones, and health education for all smokers. We also provide community-based spirometry pulmonary function test (PFT) and education to smokers. If smokers whose post-bronchodilator FEV1/FVC\<0.7, they will be spirometry-defined COPD patients and will be encouraged to seek treatment and medication to the superior hospitals. Additionally, we provide (1) another digital health intervention programs to smokers with mental health issues; (2) CBT-based health education for study participants with abnormal BMI; (3) active recruitment into National Essential Public Health Program in China for those with abnormal blood pressure and blood glucose. Intensive follow-ups will be conducted at month 3 (telephone interview), month 6 (face-to-face with full steps of physical examination), and month 12.

Comparison: Those who are assigned in the control arm, we will ask them to finish the same COPD-SQ online questionnaire with notification of his or her COPD high risk status and a face-to-face survey. No physical examinations, community-based pulmonary function tests will be given.

Outcomes: The primary outcomes are self-reported average number of cigarettes consumed per day, smoking dependence index, and CO measurement.

Introduction to Smoking Dependence Scale: Chinese version of Fagerström test for nicotine dependence (FTND), ranging from 0 to 15, the higher the score, the severer nicotine dependence will be. Also Heaviness of Smoking Index (HSI) will also be measured, ranging from 0 to 6, the higher the score, the worsen the nicotine dependence will be, 1 year|Carbon Monoxide Measurement, Definition: CO measurement by the portable CO machines Variable type: Continuous; Measurement: CO detector., 1 year
Secondary Outcome Measures: Self-rate health status, Definition: General self-assessed health status; Variable type: Continuous; Measurement: EQ-5D scale; Introduction to EQ-5D-5L scale: The 5-level EQ-5D version (EQ-5D-5L) was introduced by the EuroQol Group in 2009 to improve the instrument's sensitivity and to reduce ceiling effects, as compared to the EQ-5D-3L. The scale could be transferred to health utility value, ranging from 0 to 1 continuously. 0 represents death and 1 represents perfect health., 1 year|Number of Chronic Conditions Controlled, Definition: Among 7 objectively measured health conditions (COPD, asthma, depression symptoms, anxiety symptoms, BMI, hypertension, type 2 diabetes), the number of chronic conditions controlled; Variable type: Counting data; Measurement: Through objective physical examination or validated scale;, 1 year|Physical proof of cigarettes, Definition: Can you show me your cigarettes?

Introduction to WPAI-GH : Work Productivity and Activity Impairment-General Health (v2.0) Chinese version.WPAI outcomes are expressed as impairment percentages, with higher numbers indicating greater impairment and less productivity, i.e., worse outcomes, as follows:

Questions:

1. = currently employed
2. = hours missed due to health problems
3. = hours missed other reasons
4. = hours actually worked
5. = degree health affected productivity while working
6. = degree health affected regular activities

Scores:

Multiply scores by 100 to express in percentages.

Percent work time missed due to health: Q2/(Q2+Q4)

Percent impairment while working due to health: Q5/10

Percent overall work impairment due to health:

Q2/(Q2+Q4)+\[(1-(Q2/(Q2+Q4)))x(Q5/10)\]
