To choose the study trials, a two-stage group testing strategy was used

The sample dimensions is proportionally allotted to the size of MSM in each state. We provided merely Battambang and Siem Reap provinces because few MSM covered by the SAHACOM got too small in other provinces as soon as the midterm review was actually conducted. Also, the full total range MSM inhabitants within these two provinces displayed over 70 percent for the final amount of MSM included in the focused prevention training regarding the SAHACOM.

We used communes in each state once the smallest device for any sampling processes. A commune is within the study whether or not it was according to the insurance with the SAHACOM tools for around 12 months ahead of the data collection. Amusement sites or hotspots, where MSM congregated, were determined by our community-based applying partners and/or created by making use of geographical info program mapping previously manufactured by our very own analysis staff. The sites or hotspots provided nightclubs, discotheques, sport organizations, charm salons, roadways, parks, private houses, and specific forums. MSM were contacted within venues or hotspots, in which face-to-face interview happened to be done. Becoming included in this study, people must: (1) getting elderly 18 age or older; (2) self-report as an MSM; (3) has lived in a catchment part of the SAHACOM for at least year as identified by outreach people; (4) manage to provide permission to sign up for the study; and (5) be able to present themselves on the day in the data range. MSM have been emotionally and/or physically also sick to sign up comprise excluded through the study.

Information range knowledge

All interviewers and industry superiors had been trained for 2 weeks on information collection techniques, and one time got allocated for instrument pretesting and expression. Working out covered required skills like meeting method, privacy, and privacy confidence. The analysis protocol and technology were in addition reviewed throughout workout sessions to allow the group customers to get carefully familiar with all of them. We also provided quality assurance skills particularly rechecking and evaluating the forms after administration and resolving issues that might happen throughout the fieldwork. Field superiors had been motivated to perform regular classes with interviewers throughout the study period to review advancement and communicate any problems taking place while in the information range.

Survey development

An organized questionnaire was first created in English and translated into Khmer, the nationwide code of Cambodia. Another translator back-translated they into English to ensure that the a€?content and spirita€? of each earliest object comprise preserved. Clear guidance and information happened to be dealt with in order to prevent any confusion throughout the interviews. Standardized tools were adapted from earlier research in the same inhabitants [18, 26], the newest Cambodia group and wellness review [27], also research in Cambodia [28a€“34]. For information on the questionnairei»?, kindly see a€?Additional file 1.a€?

Prior to the data range, a pilot learn was actually performed with 10 MSM in Phnom Penh to make sure that the text and materials happened to be culturally appropriate and demonstrably understandable when it comes to study individuals. Needed adjustments had been generated based upon comments from pilot research and remarks from experts and enthusiasts doing HIV among MSM in Cambodia before finalizing the questionnaire.

Socio-demographic qualities included age, marital condition, several years of proper education complete, biggest occupation, ordinary monthly money, live conditions, and private understanding about sex character. Yes/no concerns were used to gather information on a number of intimate behaviors, like sexual strategies and condom and lubricant use with different associates such typical feminine couples, typical male associates, female sex workers, male gender professionals, female people, and male consumers before three months. Respondents happened to be furthermore interrogate about HIV-related education they gotten in the past half a year, STI symptoms and healthcare searching for behaviour when it comes to symptoms prior to now 3 months, and illegal drug utilization in days gone by six months.

Facts admission and analyses

Epi Data version 3 (Odense, Denmark) was used for facts entryway into a computerized databases, and SPSS type 22.0 (IBM enterprise, ny, United States Of America) was applied for every facts analyses. Increase information entry got sang to attenuate entry errors. Descriptive analytical analyses were done to calculate methods and standard deviations (SD) for statistical variables and frequencies (per cent) for categorical factors. Chi-square test or Fishera€™s precise examination were utilized for categorical factors and matched Studenta€™s t-test for continuous factors to compare socio-demongraphic personality of respondents and end result signs to detect variations from midterm to endline. Two-sided p-values


Socio-demographic traits

STI symptoms, care-seeking actions, and illicit drug utilize


This study shows significant alterations in a few key end result signals from midterm to endline. Considerable effects associated with the SAHACOM might be seen in the decrease in the amount of intimate associates and paying for intercourse. The percentage of MSM who reported having STI symptoms decreased, as the proportion concerning MSM that reported seeking take care of their latest episode of STIs increased significantly. Illicit medication utilize in addition diminished dramatically. But bad changes ought to be observed. These incorporated the reduction in reported latest HIV examination price therefore the boost in participation in sex operate and sexual intercourse with standard female couples. It’s worth-noting that, although no considerable changes got found in condom and lubricant used in all connections from midterm to endline, condom usage with normal male partners increased considerably from just 27 % at standard this season [20] to 62.4 percent at midterm and 64.7 percent at endline. But while this information is useful for regimen implementers, this comparison need to be fashioned with extreme caution considering that the speed of condom need at baseline ended up being from program facts compiled through desk product reviews and consultative group meetings with essential stakeholders [20], without details on the info range strategies can be obtained.
