  We present a computer simulation study of influence of the confinement on the
density anomaly in the system with isotropic core-softened potential which is
used for a qualitative description of the anomalous behavior of water and some
other liquids. We have found that a maximum temperature of the density anomaly
region along an isochor $\rho=0.5$ does not depend on the pore width. We have
shown that a decrease in the width of the confining slit pore leads to an
increase in the crystallization temperature and as a result the local density
distribution is mostly controlled by the particle-wall interaction, which leads
to the depression of the density anomaly.
