“…Study populations range from representative samples of the USA and EU states [14][15][16][17], to large samples with civil servants from the UK and Brazil [10,18 & ,19], to children and adolescents [20 & , 21-23], to middle-aged and elderly populations [24][25][26][27][28][29], to ethnically diverse samples [8,30,31], to populations from developing countries [32][33][34][35], to immigrants [36][37][38], to pregnant women [39] and different clinical samples [40][41][42][43][44][45].
