Objectives

This study aims to evaluate the prevalence and associated factors of lower back pain (LBP) among farmers, rickshaw pullers and office workers in Bangladesh, while also investigating potential contributors within these occupational groups.

Design

This cross-sectional study aimed to determine the prevalence of LBP, associated factors and management procedures among farmers, rickshaw pullers and office workers in Bangladesh through face-to-face interviews.

Setting

The study was conducted in different parts of the Bogura district in Bangladesh.

Participants

A total of 396 participants were included in the final analysis, all the participants were men and adult in age.

Main outcome measurements

Data were collected using a semi-structured questionnaire based on previous research. Bivariate and multivariable logistic regression analyses were performed to identify significant associations.

Results

The prevalence of LBP was found to be 42.7% among the participants. Farmers and rickshaw pullers had approximately four-times and three-times higher odds of experiencing LBP compared with office workers. Other significant factors associated with LBP included living in a nuclear family, having a normal body weight, lacking professional training, having a chronic disease, having a family history of LBP and experiencing numbness in the legs or feet. The majority of respondents sought medical attention and took medication for their LBP.

Conclusion

The study underscores occupational differences in LBP prevalence, emphasising the necessity for tailored interventions and occupational health policies. Identifying specific risk factors and management practices in these professions can aid in developing effective prevention strategies and enhancing healthcare services.

Identification of quantitative trait loci associated with bacterial spot race T4 resistance in intra-specific populations of tomato (<i>Solanum lycopersicum</i> L.<i>)</i>

by Pragya Adhikari, Muhammad Irfan Siddique, Frank J. Louws, Dilip R. Panthee

Bacterial spot of tomato is a serious disease caused by at least four species and four races of Xanthomonas- X. euvesicatoria (race T1), X. vesicatoria (race T2), X. perforans (race T3 and T4), and X. gardneri, with X. perforans race T4 being predominant in the southeast USA. Practical management of this disease is challenging because of the need for more effective chemicals and commercially resistant cultivars. Identification of genetic resistance is the first step to developing a disease-resistant variety. The objective of this study was to identify quantitative trait loci (QTL) conferring resistance to race T4 in two independent recombinant inbred lines (RILs) populations NC 10204 (intra-specific) and NC 13666 (interspecific) developed by crossing NC 30P x NC22L-1(2008) and NC 1CELBR x PI 270443, respectively. Seven QTLs on chromosomes 2, 6, 7, 11, and 12 were identified in NC 10204. The QTL on chromosome 6 explained the highest percentage of phenotypic variance (up to 21.3%), followed by the QTL on chromosome 12 (up to 8.2%). On the other hand, the QTLs on chromosomes 1, 3, 4, 6, 7, 8, 9, and 11 were detected in NC 13666. The QTLs on chromosomes 6, 7, and 11 were co-located in NC 10204 and NC 13666 populations. The donor of the resistance associated with these QTL in NC 10204 is a released breeding line with superior horticultural traits. Therefore, both the donor parent and the QTL information will be useful in tomato breeding programs as there will be minimal linkage drag associated with the bacterial spot resistance.
