Descriptive and inferential analyses were performed 21 22 23 as appropriate. Univariate logistic regression was used to analyze the 24 25 association of variables with treatment delay among migrant PTB patients. 26 27 Multi-logistic regression model was developed to further assess the impact 28 29 of variables on treatment delay. 30 31 Results Of 314 migrant PTB patients, 65.6% experienced treatment delay. 32 33 The migrant patients whose household income level, whose diagnosis 34 http://bmjopen.bmj.com/ 35 symptom severity, cognition on whether TB was curable or not and 36 37 knowledge about TB free treatment policy were factors significantly 38 39 associated with treatment delay. 40 41 Conclusions Economic status and cognition on TB cure of migrant PTB 42 on September 30, 2021 by guest.

Implementing TB-related 44 45 health education and TB free treatment policy promotion was essential to 46 47 better control tuberculosis among migrants. 48 49 50 51 52 Key Words 53 54 Tuberculosis, migrant, treatment delay, cross-sectional study ,China 55 56 57 58 59 60 2 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml Page 3 of 18 BMJ Open BMJ Open: first published as 10.1136/bmjopen-2014-005805 on 22 December 2014.

Downloaded from 1 2 3 4 Introduction 5 6 China has highest burden of tuberculosis (TB) and it ranks second 7 8 among the 22 high-burden countries in the world (1). Since 1991, China has 9 10 implemented Directly Observed Treatment-Short Course (DOTS) strategy 11 12 and it has universally covered TB patients (2). As a result, the cure rate of 13 14 active TB cases has reached over 90% (3). However, DOTS for migrant 15 For peer review only 16 population remains as one of the main challenges in China TB control (4-5). 17 18 In 2011, the number of migrants in China has increased to 230 million, 19 20 and it would increase continuously in the up-coming decades (6). As 21 22 23 reported in other studies, TB management among migrants is more difficult 24 25 than that of local residents due to migrants “migratory” nature, poor 26 27 financial conditions, low education level and weak awareness of TB, which 28 29 presents an important barrier for National TB Control Program in China (4-5, 30 31 7). 32 33 Management of TB patients among migrants which involves early 34 http://bmjopen.bmj.com/ 35 diagnosis and timely initiation of treatment is crucial to reduce transmission, 36 37 morbidity, mortality and development of drug resistance (8-11). Many 38 39 studies have reported the length of time from onset of symptoms related to 40 41 TB to diagnosis of PTB and risk factors for the delay (12-15). However, to 42 on September 30, 2021 by guest. Protected copyright. 43 the author’s knowledgement, few studies have documented the length of 44 45 time from the time of PTB diagnosis to the start of anti-tuberculosis 46 47 treatment among migrant PTB patients, and few have reported on risk 48 49 factors for this delay. Hence treatment delay among migrants is of a high 50 51 52 priority among topics for study in China TB control. 53 54 The objective of this study is to describe treatment delay among migrant 55 56 PTB patients in Shandong, China, and to identify factors associated with 57 58 treatment delay, so as to provide an evidence for the development and 59 60 4 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml Page 5 of 18 BMJ Open BMJ Open: first published as 10.1136/bmjopen-2014-005805 on 22 December 2014.

DOTS 13 14 strategy for TB was introduced in the 1990s and is now 100% available in 15 For peer review only 16 all counties (districts) in Shandong province. By the end of 2008, Shandong 17 18 had about 6.91 million migrants.A total of 12 counties/districts (including 19 20 Huaiyin District, Lixia District, Dongying District, Guangrao County, 21 22 23 Penglai County, Laizhou County, Zouping County, Chengyang District, Jimo 24 25 County, Luozhuang District, Lanshan District, Gaomi County) were selected 26 27 as study sites after considering the larger number of migrants in these 28 29 counties (districts) and the feasibility of the study implementation. 30 31 The participants should meet the following selection criteria: 1) They 32 33 were smear-positive migrant PTB patients registered in county TB 34 http://bmjopen.bmj.com/ st 35 dispensary(CTD) of the 12 sampling sites during the period from August 1 36 st 37 2007 to July 31 2008; 2) If the patients were being treated, the treatment 38 39 time must be over 1 month; 3) If the patients had finished normal treatment, 40 41 the closure must happen within 6 months.
