    Nutrition in early childhood and its long-term functional significance. Symposium. Anaheim CA USA, 1992/04/06.

    A follow-up study (1988-89) was carried out in 364 rural Guatemalans, 11-27 y of age, who earlier had participated in a nutritional supplementation experiment.

    Among its objectives was the assessment of the long-term effects of the nutrition intervention on physical work capacity.

    Subjects and their mothers from two villages had available a high-energy, high-protein supplement (Atole : 163 kcal/682 kJ and 6.4 g protein per serving or 180 mL), whereas in two other villages a low-energy, no-protein supplement (Fresco : 59 kcal/247 kJ per 180 mL) was provided.

    Consumption was ad libitum.

    MaXimum oxygen consumption (VO2max) at follow-up was significantly greater in Atole compared with Fresco subjects of both sexes.

    In subjects 14-19 y, exposed to supplementation throughout gestation and the first 3 y of life, Atole males had a slgnificantly higher VO2max (2.62 L/min) than Fresco males (2.24 L/min), the differences remaining significant even after controlling for body weight and fat-free mass ; also, there was a significant positive relationship between amount of supplement consumed and VO2max.

    The supplementation effect in females of similar age was not statistically significant.

    It is concluded that early nutritional improvements can have long-lasting effects on physical performance.
