“…and in 1978 Bray included pregnancy as one of four potential endocrinological causes in his aetiological classification of obesity. Not surprisingly, overweight mothers often cite pregnancy as the root cause of their obesity (Gurney, 1936;Mullins, 1960;James & Bisdee, 1982;Bradley, 1985;Abraham, 1989;Lean et al 1989;Ohlin & Rossner, 1990), and weight gain during pregnancy has become an increasing concern for women who want to avoid obesity and regain a fashionable, slim figure after they have had children (Baric & MacArthur, 1977;Feigenberg & Schiller, 1977;Orr & Simmons, 1979;Harrison & Hicks, 1983;Palmer et al 1985;Dawes et al 1992;Franko & Walton, 1993).
