“…A higher share of pregnant women consuming alcohol has been found in European countries such as Spain and Norway, where occurrence of 23% has been reported (Alvik et al, 2006b;Palma et al, 2007); the corresponding figure for Denmark is 45% (Nybo-Andersen et al, 2012) and for France 47% (Malet et al, 2006). It should be noted that these studies have used different cut-offs for drinking, such as any drinking at all (Balachova et al, 2012;Nybo-Andersen et al, 2012;Palma et al, 2007), drinking more than 1 standard drink (SD) (Tamaki et al, 2008) or more than one SD in the past 30 days (CDC, 2012). Further, the data collection methods differ between the studies, some using telephone interviews (CDC, 2012;Nybo-Andersen et al, 2012), others questionnaires (Alvik et al, 2006a) and face-to-face interviews (Balachova et al, 2012;Malet et al, 2006;Palma et al, 2007).…”
