[Approach to Childhood Obesity in Spain. A comparison among autonomies].

Objective: Childhood obesity represents a serious public health problem and given its multifactorial nature and its consequences; it is necessary to carry out an effective approach. The Spanish system of autonomies, with delegated powers, could accentuate inequality in its approach. The objective of the study was to know the existence or not of these inequalities.

Urinary concentrations of bisphenol A, parabens and benzophenone-type ultra violet light filters in relation to sperm DNA fragmentation in young men: A chemical mixtures approach.

People are daily exposed to multiple endocrine disruptor compounds (EDCs) that may interfere with different molecular and cellular processes, promoting a potential estrogenic, androgenic, or anti-androgenic state. However, most epidemiological studies attempting to establish relationships between EDCs exposure and health effects are still considering individual compounds. A few studies have shown associations between exposure to individual non-persistent EDCs and sperm DNA fragmentation (SDF) in different male populations.

Sugar-sweetened beverage intake in relation to reproductive parameters in young men.

Background: There has been a decrease in sperm concentration in recent years. Concurrently, there were important dietary changes, including an increase in sugar-sweetened beverage intake (SSB). The relation between SSB and male reproduction functions in humans are barely described in the literature.

Associations between urinary concentrations of bisphenol A and sperm DNA fragmentation in young men.

Background: Bisphenol A (BPA) is one of the most common endocrine disruptor compounds in our environment, promoting a xenoestrogenic state. Numerous studies have shown a relationship between exposure to BPA and male infertility problems. Spermatic DNA integrity is a critical factor for the correct transmission of paternal genetic material to the embryo.
