RESUMO

A Nutrition Screening Form (NSF) was designed to identify lifestyle risk factors that negatively impact fertility and to provide a descriptive profile of 300 female infertility patients in a private urban infertility clinic. The NSF was mailed to all new patients prior to the initial physician's visit and self-reported data were assessed using specific criteria to determine if a nutrition referral was warranted. This observational study revealed that 43% of the women had a body mass index (BMI) <20 or ≥25 kg/m(2), known risks for infertility. Almost half reported a history of "dieting" and unrealistic weight goals potentially limiting energy and essential nutrients. A high number reported eating disorders, vegetarianism, low fat or low cholesterol diets, and dietary supplement use. Fourteen percent appeared not to supplement with folic acid, 13% rated exercise as "extremely" or "very active", and 28% reported a "high" perceived level of stress. This preliminary research demonstrated that a NSF can be a useful tool to identify nutrition-related lifestyle factors that may negatively impact fertility and identified weight, BMI, diet, exercise, and stress as modifiable risk factors deserving future research. NSF information can help increase awareness among health professionals and patients about the important link between nutrition, fertility, and successful reproductive outcomes.

RESUMO

Ask any Olympian about their quest for gold and they will almost always tell you it's not really about the gold - it's all about the journey. What they learned and how they felt at the time of their successes, disappointments and failures is ultimately what challenged them to find the courage to truly believe in themselves and achieve their personal best. As dietitians, we are also like Olympians as each of us seeks personal success in our journey through life. It is no surprise that it takes knowledge and experience to become a champion. "Going for the Gold" highlights some of the milestones and challenges in the author's career and focuses on (her) two specialties, sports nutrition and nutrition and infertility, both relatively new to the dietetics field. Having a successful private practice means building a solid foundation of knowledge, excellent clinical and communication skills, finding the courage to "think outside of the box", a compassion for others and a strong work ethic to fulfill goals that benefit both clients and the profession. As the author recounts her journey, dietitians are reminded that there is no straight path to success, and in their quest for gold not to forget to give back...to their profession, their family, their country and their environment.

RESUMO

It is the position of the American Dietetic Association, Dietitians of Canada, and the American College of Sports Medicine that physical activity, athletic performance, and recovery from exercise are enhanced by optimal nutrition. These organizations recommend appropriate selection of foods and fluids, timing of intake, and supplement choices for optimal health and exercise performance. This updated position paper couples a rigorous, systematic, evidence-based analysis of nutrition and performance-specific literature with current scientific data related to energy needs, assessment of body composition, strategies for weight change, nutrient and fluid needs, special nutrient needs during training and competition, the use of supplements and ergogenic aids, nutrition recommendations for vegetarian athletes, and the roles and responsibilities of sports dietitians. Energy and macronutrient needs, especially carbohydrate and protein, must be met during times of high physical activity to maintain body weight, replenish glycogen stores, and provide adequate protein to build and repair tissue. Fat intake should be sufficient to provide the essential fatty acids and fat-soluble vitamins, as well as contribute energy for weight maintenance. Although exercise performance can be affected by body weight and composition, these physical measures should not be a criterion for sports performance and daily weigh-ins are discouraged. Adequate food and fluid should be consumed before, during, and after exercise to help maintain blood glucose concentration during exercise, maximize exercise performance, and improve recovery time. Athletes should be well hydrated before exercise and drink enough fluid during and after exercise to balance fluid losses. Sports beverages containing carbohydrates and electrolytes may be consumed before, during, and after exercise to help maintain blood glucose concentration, provide fuel for muscles, and decrease risk of dehydration and hyponatremia. Vitamin and mineral supplements are not needed if adequate energy to maintain body weight is consumed from a variety of foods. However, athletes who restrict energy intake, use severe weight-loss practices, eliminate one or more food groups from their diet, or consume unbalanced diets with low micronutrient density, may require supplements. Because regulations specific to nutritional ergogenic aids are poorly enforced, they should be used with caution, and only after careful product evaluation for safety, efficacy, potency, and legality. A qualified sports dietitian and in particular in the United States, a Board Certified Specialist in Sports Dietetics, should provide individualized nutrition direction and advice subsequent to a comprehensive nutrition assessment.
