“…In order to improve representativeness, survey weights were generated to adjust for deviation of the target population to the German adult population based on estimates of the German Federal Statistical Office of Germany for 2009. This included a design weighting to (i) number of telephone numbers in the household and (ii) number of persons in the household, and additionally a weighting post-stratification to (iii) age, (iv) sex, (v) region and (vi) education (standard classification: ISCED) [27, 28]. Unless otherwise stated, all statistical analyses account for the weights.…”

SUMMARYPopulation-based estimates of incidence and risk factors for acute gastrointestinal illness (AGI) are important for infectious disease surveillance and healthcare planning. We conducted a nationwide representative cross-sectional telephone survey of 21 262 adults over a 12-month period during 2008-2009 in Germany. Participants were asked if they had either AGI-related diarrhoea or vomiting in a 4-week recall period. We estimated 0·95 episodes/person per year (95% confidence interval 0·90-0·99), corresponding to 64·9 million episodes of AGI annually in adults, which results in 24·5 million outpatient visits, 19·9 million hospital days and 63·2 million days of work lost. We observed an overall declining trend of AGI with increasing age. Diarrhoea was more often reported than vomiting. The mean duration of illness was 3·8 days and did not differ between age groups. Social factors seemed to be weak predictors compared to state of health and health behaviour characteristics. This study allows international comparisons and contributes to the estimation of the global burden of AGI.

“…Representativeness at the individual level is ensured by using the "next or last birthday method". The data collected in this way is weighted according to age group, gender distribution and region / federal state (Land), taking into account the number of people and telephone lines in the household and adjusted to the population structure in the survey year (see also v. d. Lippe et al, 2011;Schmich et al, 2012).…”

“…Literature suggests that around 12 to 15 call attempts is the optimal number for fixed CATI surveys (Srinath et al . 2001;Hansen 2008;Schmich & Jentsch 2012) . Although the likelihood of a successful call decreases with the number of attempts (e .g .…”

This study explores the effects of call attempts and time periods on call outcomes and sample composition. A mobile computer-assisted telephone interview survey was conducted to collect data from adult mobile phone users about use and attitudes towards mobile phones; paradata regarding call dispositions, time and day of the week of calls and number of call attempts was also available. The first call contact rate was approximately 27% and varied significantly across time periods; the rate fell to below 20% for the second call. Weekend time periods yielded higher contact rates than weekday time periods. The interview rate on the first call was 12% and decreased steadily in subsequent calls. Mobile phone numbers that yielded call rejection, voicemail or were busy on the first call were very difficult to convert into interview on the second call. The number of call attempts and time period of the calls affect sample composition, namely in relation to respondents' age, educational level and area of residence. Future research and practical implications of the findings for mobile CATI surveys are discussed.
